Why was this done? I don't know.

AIUI, because all Unix kernels treat local I/O as arbitrarily fast, hence "local" files (which might in fact be NFS-mounted from another continent) are not usefully pollable.

You can usefully poll pipes, fifos, sockets, most recent-ish Linux APIs (e.g. inotify, epoll, timerfd, kdbus), and probably their equivalents on non-Linux. Notably, "regular files" are not on that list (and I don't think directories are either).
