I feel like it may constitute a separate device class than a dumb-phone but I don't know how much is marketing versus reality.
If your goal is to overcome a phone/internet addiction, or just disconnect, then the LP2 will definitively help you achieve that! Your going to have to give some stuff up (No Spotify, no Directions yet), and deal with texting that worse then a smart phone but better then a number pad. But to me its definitely worth it.
I think the LP2 will eventually provide the same stuff that the original author gets from his Garmin watch and GSM Calls phone, which is pretty neat!
Very solid devices for cutting back internet dépendance or for traveling without but still having the basics.
I'd imagine heat tolerance and impact resilience would be more important than slimness and lightweight for these devices if they're intended to be used like say, at a foundry.

Try looking up other KaiOS phones. There aren't many.
but I realized I barely talk on the phone, I just use it for texting. Thinking old blackberry format would be better, as I prefer the keyboard.
