If you're only using a console because you broke your WM config (or something similar) then I imagine it's quite intimidating.

"help" is the most likely first place looked for assistance in such circumstances I'd imagine.

I think many Linux users have hacked around and messed up settings. This line was meant for those who have been in that situation, to say "hey btw, that screen was a login shell" (even took a picture of it). Just adds a little context, it doesn't resonate with everyone.

I think booting to a console when you expect a desktop can be scary, especially if you don't know how to undo whatever you did.
