Not exactly.  You've pinpointed the wrong target.

First of all, we want people to support Python 3.  Removing support for
Python 2 is a secondary goal.

Flagging packages that support Python 2 in addition to Python 3
and cause no trouble in py2 cleanup is doubtful.

Flagging packages that support 2+3 because of their revdeps is not
helpful at all.  It's just noise to the maintainer who can't remove py2
because of revdeps.

Flagging dev-python/pypy* which needs py2 but is entirely outside
the eclass system is not helpful at all.
