Mostly because it seemed somewhat sad to require every extension to have
version-specific ifdefs around that, particularly because it's not hard for us
to infer.

I think there might be other use cases for the backend to provide "extension
scoped" information, FWIW. Even just providing the full path to the extension
library could be useful.
