I'm kind of confused here, so i feel like i missing something. The way this is written makes feel feel like you you don't think the junior devs need to become competent at those high level tasks over time? Otherwise, how do they become senior devs if not by things like "gradually delegate higher level work, see what happens, help them learn by mentoring them based on results". It's not like they read a book and suddenly know how to do that.

"hard enough that explaining them to juniors is not the most productive" I strongly doubt this. Most of the differences i've seen over the years are in approach to complexity, and not level of complexity themselves.
