True, but that wasn't the question.

However, to add a bit of sanity to this thread, please consider
that PEP 294 is still open - it survived the recent spate of PEP
rejections and closings. It suggests extending the types module
to include all types, including those in the new module (which the
OP seems to have overlooked,) and then depreciating the new
module.
