But the blind spot of not thinking in terms of genexps is for "old"
Python developers, not new ones who started off with them and probably
don't use listcomps that often (I know I don't anymore). Documenting
this specific suggestion leads down a rabbit hole of adding coding
suggestions all over Python for how we feel something *should* be used
when it isn't really our place to do so.

But if someone wants to submit a patch to fix the docs another core
developer might be willing to make the change other than me (I'm -0 on
the change).
