We usually expose low-level, file descriptor-related functions in the os module and then provide high-level wrappers in Python. The approach is most flexible and allows 3rd parties to build on top of the raw file descriptor, too. I opened a BPO and created https://github.com/python/cpython/pull/20930 to implement a low-level interface to glibc's eventfd() function.
