FWIW, I regularly delete revisions on some files. These are large binaries,
and after some time, most of the revisions are not necessary anymore and
just take up unnecessary space. I'd miss that feature. I don't know how
easy it would be to delete them from the SQL database without breaking
anything (neither the integrity of the database, nor of the remaining
revisions).
