Though if wave and sndhdr were currently PyPI-only and someone came to python-ideas/python-dev saying "These modules ought to be in the standard library", I doubt they'd get a huge amount of support. Of course, since they're currently in the stdlib, there's absolutely no reason to *remove* them, but any similar modules are likely to stay pip-gettable rather than autoincluded. In contrast, something like Lib/email.py is providing functionality that heaps of Python scripts want - sending or parsing emails is pretty common, so it makes good sense to have that in the stdlib.
