Since 1993, aifc.openfp has simply pointed to aifc.open as a matter of backwards compatibility. See https://github.com/python/cpython/commit/7bc817d5ba917528e8bd07ec461c635291e7b06a for the exact change. aifc.openfp is both undocumented and untested, and in looking at doc coverage I decided it's better to deprecate it since it's silently been there for 25 years.
i was going to do them as separate bugs and PRs per module, but if one is fine then i can do that. Updating the title as well since nothing is beings removed (was originally going to suggest skipping to removal but won’t do that).
audiotests.py. Create class AudioMiscTests and inherit classes AifcMiscTest, SunauMiscTest, WaveMiscTest from it instead of AudioTests. There is more work because there was no base for misc tests, but this will make adding other common misc test easier.
