On Unix platforms, you should always have FDCLOEXEC. If there were such a platform without FD inheritance support, then it would probably make sense to make it a no-op

Ok, and os.get_inheritable() can also always return False.

It would prefer to fail with a compiler error is the platform is unknown. A platform might support FD inheritance, but with something different than fcntl() or ioctl() (ex: Windows).
