Glib already seems to use several hacks to work around the limitations of
kqueue and Glib offers far fewer features than inotify. Trying to emulate
inotify on top of kqueue therefore seems like a futile approach. Unless the
*BSD folks implement inotify (or at least something similar) in their kernels
I don't think we can seriously expect inotify to become a portable solution.
Glib meanwhile has a portable implementation and is already used (optionally)
in GNU Emacs. I don't think there is a risk of Glib abandoning kqueue support
and even if they did then we could look at the issue again.
