It's not an overkill in the technical sense (I know the concept of
"cheap copies").
Maybe overkill is not the right word at all. But from a user's point of
view it may be easier to understand what a simple "cvs tag" does as to
explain that you have to do a copy operation (and so create a new
revision number) just to "tag" a certain revision to make it easier to
look up later.
Let me say it this way: If I was able to remember what state of my
project a revision represents, I would not need this copying at all. But
I am not because revisions are plain numbers with no mnemonic meaning.

Are per-directory permissions really a solution here? A user must be
able to copy to the tags directory to let him create his tag, but he
must not be allowed to modify this tag later (except from deleteing it
perhaps).
