Yes, this was also a problem. Sometimes, the promised polling on mounted
filesystems didn't work reliably.

There were also bugs which have restricted use of gfilenotify.

And there are also reservations by people, who do not want to use glib /
gio infrastructure.

Due to the existence of inotify and kqueue monitors in Emacs, the only
major use of gfilenotify seems to be in Cygwin.
