I'm not necessarily disagreeing here.

It all depends on how ExtensionFileLoader is meant to be used. Should it try to support extension modules in the narrow sense (hand-written .c files) or in the broad sense (any kind of extension module, possibly auto-generated).

Doing that properly in Cython would almost certainly need PEP 489 support though (Cython is in the process of implementing that, but apparently it's not easy)
