Possibly. The point is that (a) admins will often see
individual revs
they want to zap (prior to notifying the oversighters, usually - but
take them out of public view ASAP) (b) it needs to be easily undoable
in case of error (c) it needs not to have the effect deleting a page
with a zillion revs does.
It could be done so admins can delete revisions in such a way that
only oversighters can undelete them. That would solve (a) while
failing (b). Allow admins to undo only their own such deletions would
help. This would, of course, be in addition to deleting revisions in
such a way that any admin can undelete them.
Making the oversighters more of a bottleneck is the
problem I see
there. Giving admins the power to delete individual revs wouldn't IMO
be a great change from now - they currently do it, they just have to
do it by deleting the page and selectively restoring all except the
bad revs ... which seems to me more prone to error.
A very good point. There's no way this feature can really make things worse...
