Probably just an oversight. A no-op future import is trivial to add and ignore.

There is one (annotation_typing) that controls whether Cython reads annotations as types or not (which isn't what you're asking for). Apart from that, since there is no future unimport, there should probably be a way to get either behaviour, regardless of the default.
