Yes, that's the rationale for keeping names like “map” and “flatMap” as
they are.

I don't think so.  First, I think it's probably impossible to come up
with good guidance for that; at some point it's a matter of using
judgement.  Second, we want to keep the guidelines as simple as
possible, so they're easy to follow.
