How large a number?  I have very little basis for more than wild
guessing here; I rarely use sparse files, and even more rarely use
files sparse enough to make a significant difference from a quota point
of view.

Furthermore, those few uses are generally administrative, the kind of
thing that either is on a non-quota filesystem or is owned by a user
who can be exempted from quotas without harm (eg, root).

Do you have experience or studies indicating that this is another
respect in which I am an outlier?
