  If I understand the problem at hand, they are really interested in
notification when running out of free space. Using quota for that doesn't
seem ideal since that tracks used space per user, not free space on fs as a
whole.

But if I remember right there were discussions about ENOSPC notification
from filesystem for thin provisioning usecases. It would be good to make
this consistent with those but I'm not sure if it went anywhere.
