Because I want to provide (at least) two wheels: a wheel for linux
users with the C extension compiled and a generic wheel in pure python
as a fallback for any other architecture.

If I make the extension optional, as far as I know, only one wheel is
produced: the wheel with the extension if all is successful, or the
pure py wheel.
