We tried with a change for fossil to tell about changes, but we
found that a change (suggested by rsc in the source) to propagate
mtimes upwards in the tree up to the root made it trivial to learn which
files changed since the last scan. BTW, our poll is not using that feature.

I don't think you are missing anything, seems it would be nice to have a 
way to connect to a file server and say "tell me about metadata changes".
