How do you detect this?
Also, what about a new slot for python-2? E.g. 2.7?
And do you want to add a special rule to portage just for the special case of python instead of the
ebuilds/eclasses having the issue?

There is currently the additional issue with distutils.eclass, which does directly add
"dev-lang/python" to the dependencies, if there is nothing additional defined. So even e.g.
dev-libs/protobuf does pull in python-3*, also there is no indication, that it will even work with
that version.
