The Guitar Grimoirr scale book is 200 pages!
Edit: the minor scale doesn't count because C major = A minor if you start on A, fair enough, forget that one.
It might actually count since the harmonic minor exists. But this is just stressing the point that all of those "separate" scales might perhaps be best introduced as simple variations of the usual diatonic scale. Then sure, you might want to practice them a little bit, but at least you should have "learned" them in that you are not wondering what you're supposed to play.
The prefix of "diatonic" is "dia" ("through"), not "di" ("two"), but nobody really knows what exactly its origin (διάτονος, "diátonos") was supposed to mean[1]: it's probably either something like "through the tones" or "stretched out tones".
The second meaning is closer to the modern definition we have for diatonic: the 7 (out of 12) notes are selected to be as stretched out as possible in the octave, that is, each adjacent note is either 1 or 2 semitones apart, and the two 1-semitone-apart pairs are as far as possible from each other (note that the second requirement excludes e.g. the ascending melodic minor[2] from being considered diatonic, even though it has 7 notes).
(If anything, I would want a "guitar learning" app to automatically come up with its own exercises, similar to ear training apps for learning to recognize intervals - and using something like a spaced repetition approach to evaluate how the user is doing.)

There is definitely theory to how they are constructed, and you are right that the shifts and adjustments can be derived if you think about it and practice it. But that's just a longer way to the five patterns.
I've since gone back and learned a bit of music theory as an adult and it's been super helpful understanding the underlying principles so I can work things out vs. having to just memorize things without understanding why they work.
I think then you can go practice the various scale patterns and get good at them with the knowledge that you can always work out the scale from first principles if you need to.
Different strokes for different folks though I guess, I'm sure there's an argument to be made for not overwhelming folks with too much theory out of the gate. Not sure if I had started with a bunch of theory if I would have stuck with it when I was younger.
Thing is, it's not even "too much theory". It really is just a simple tone-semitone pattern and a few bare facts about how the usual guitar tuning works, that you'd know anyway if you've ever had to tune your guitar by hand. That's all it takes to make the guitar explainable from first principles. Then sure, you can practice the "patterns" all you want for convenience's sake, but you don't have to commit anything to memory that you could not figure out again from scratch if needed.
I would agree with you. I feel like watching videos where someone goes "hey, so here's this pattern that completely unlocks the neck for you, don't be stuck in a box anymore!" and all they're showing you is where the various notes in a key are along the neck (now I know that, but I wouldn't have known that before...) and it's WAY more confusing than if you just learn how the pentatonic scale works and how to find the notes in a key etc. And the funny thing is, the only reason I was stuck in that box in the first place is because of silly rote memorization without understanding why you play the various notes in a scale etc., it just feels like this thing that kind of compounds when you just learn patterns vs. just learning the underlying principles.
But again, I'm completely amateur at this stuff still, and I don't have any experience teaching other folks an instrument, so it's hard for me to say with any certainty that we should be teaching it one way or another I guess.
I agree. The downvoted op is right in a way. Guitarists have a way to make things difficult. Just learn to play the 1 octave major scale/arpeggio, and triads, then 7th shells. The guitar is relative, a 1 octave scale on a guitar is the same, on keyboard it's positional.
However it's worth mentioning that I think Berklee does teach patterns, and a few jazz guitarists say to learn it too. It almost seems like learning guitar is not as worked out as other instruments. Everybody that gets good winds up having to learn all the things other guitarists have had to figure out over years after they rote learned it.
A pattern is a way of playing a scale across the strings without having to move your hand. To play the same scale in the same key at a different position on the neck, the pattern of notes is different.
You have to learn 5 different patterns to be able to play a single pentatonic scale anywhere on the neck.
Obviously they all start at a different position if you want to use a different key - that is easy. Still 5 patterns to learn though just for that one scale.
