Recent browsing brought me to Facebook's Apache v2 licensed watchman
project:

https://github.com/facebook/watchman

With recent emacs activity in much the same space I wonder whether the
developers were aware of this work.

Nope, I didn't know that. Interesting.

With the basic functions we have added to Emacs, it could be possible to
implement a similar framework. Before doing this, we shall know intended
use cases.

Beside autorevert.el, I haven't seen use cases yet.

Could Gnus set up notifications against a directory (Maildir or nnml)?
Then it wouldn't have to scan the directory to find out what files have
been added or deleted.

Another possible use case is that `dired' and `vc-dir' could autoupdate
so you don't have to hit `g' to refresh.

A buffer for a VC-controlled file, e.g. with Git, could listen for
notifications on the directory and notice when the current branch or
other information change and at least update the modeline.

I hope these are interesting :)

For sure.

Yep. But somebody has to take the ball, and implement it. I've done it
for autorevert, likely I won't track the other cases.

Magit has something like this for git:
