I think we can remove these in 3.8. My understanding of the policy (which I cannot find: the search terms are too generic) is that if a module defines __all__, and the symbol we want to remove isn't in it, then we can remove the symbol in the next feature release without requiring a deprecation period.

If a module doesn't define __all__, then we need a deprecation period in order to remove a symbol, unless the symbol is a module, and then we can just remove it in the next feature release.
