can obliterate be used to remove a specific version of a file, such as file#2 leaving file#1?

My impression is that it only removes files, and would not apply to revisions.

On a fairly regular basis, people come to me asking if they can remove or back out a change they have submitted. I always tell them they can only fix it with another submit of the files they really want.

I know if we were desperate, we could probably edit the db files or checkpoint, but that's a major inconvenience (our checkpoint runs at midnight, and users have mentioned how inconvenient it is!)

I guess the procedure might be to truncate the journal file to before their change, then restart with the checkpoint and journal, of course if the change was not the last one, others would be lost.
