People who have Rollback permission will see a Rollback link on Recent
changes or any page's history tab.

Rollback is only a short-cut for viewing an old revision and then
saving the page as that old revision. Actually since "Undo"
functionality was introduced it is more or less redundant. (Rollback
is 1 click, Undo is 2 clicks. Also, Undo is only on page history.)

If people can view old revisions, they will be able to save them, even
if they just cut and paste. I don't think you can have a wiki and
really stop people being able to "revert" (which is what I think you
want to do?).
