The CPython/C API is not terrible but it's not all that easy to use.
For example, it's very easy to make reference counting errors.  Other
language FFI's that I've used avoid that problem to some extent.  It's
true that CPython has quite a few existing C modules that would require
rework if the API were to change incompatibly.  But I think a different
(better) API wouldn't stop people from writing new modules.
