If we're going to keep that practice, there's no point to having the
PEP: all three methods (base+extensions, pkgutil, setuptools) all
work just fine as they are, with no changes to importing or the stdlib.
In particular, without the feature of being able to drop that
practice, there would be no reason for setuptools to adopt the
PEP. That's why I'm -1 on your proposal: it's actually inferior to
the methods we already have today.
