[issue22722] inheritable pipes are unwieldy without os.pipe2

If I understand correctly, you propose to add an option inheritable parameter to os.pipe():

def os.pipe(inheritable=False):
    ...

The PEP 446 was written to fix race conditions. os.pipe(inheritable=True) would create a race condition if another thread calls fork().

What is your use case? Please elaborate.

The subprocess module makes "pass_fds" file descriptors inheritables in a safe way.
