I now think it should only be a defined return value for get_requires_for_build_sdist and build_sdist, and should have special "sorry I can't do that Dave" semantics that are different from e.g. a missing get_requires_for_build_sdist hook.
I don't think there's anything wrong with NotImplemented triggering different actions in different circumstances. It already has very context-dependent "fall back to something else" semantics for binary operators. -- Greg
