Adding whenImported would be useful, even outside of ABCs and generic
functions.

But please don't go overboard with the "and its friends" part.  That
15K zip file boiled down to a 370 line python module.  Over 200 of
those lines were to support things like module inheritance or
returning a sequence with strings replaced by the result of running
import/getattr on them.  Those uses are probably too obscure for the
stdlib.
