FA_DEALLOCATE is probably easier to implement, at least for filesystems supporting sparse files at all.

Quite so! punch should really have been in POSIX from the start, except
that sparse files were never really in POSIX per se: they were just an
efficiency hack atop seeking, so nobody seems to have thought `hey, what
if we want to make an existing file sparser than it is?'
