Let's take a "stable" user who updates (`emerge --update --deep --newuse @world`) his/her system regularly. Python 3.3 is released, added to Portage tree and eventually unmasked. PYTHON_TARGETS variable is changed to include 3.3. And suddenly `emerge --newuse @world` on stable system suggests rebuilding of every package using new eclass, because new (though disabled) USE-flags was added. And when Python 3.3 is keyworded stable, hence bringing new default PYTHON_TARGETS, user should now rebuild those packages once more, but now, at least, not uselessly. Just yesterday I had www-servers/uwsgi recompiled because of changed RUBY_TARGETS. And I even have no Ruby installed.

I had written about problems with new eclass a couple of weeks ago here. Not that anybody cares that now any user not caring about dev-lang/python explicitly would get Python 2.7 and all his modules compiled twice for no good reason (except "we can't think out more sensible default for new eclass"). Whether or not does he *really* need Python 2.x or stable and included-in-stage3 Python 3.2 suffices for him.
