What do we really gain by dumping it, though? Just add a CPython
specific test that ensures:
for key, value in xml.etree.ElementTree.__dict__.items():
self.assertIs(getattr(xml.etree.cElementTree, key), value)
and then ignore it for the next decade or so.
Programmatic deprecation is a significant imposition on third party
developers and should really be reserved for APIs that actively
encourage writing broken code (e.g. contextlib.nested) or are
seriously problematic for python-dev to maintain. For cleanup stuff,
documented deprecation is sufficient.
Something that might be worth doing (although it would likely scare
the peanut gallery) is to create a PEP 4000 to record the various
cleanup tasks (like dropping cElementTree) that are being deliberately
excluded from the 3.x series.
Cheers,
Nick.
