Actually you can.  The taginfo script in CVSROOT lists scripts that
are run to check a tag before its committed.  These scripts can
prevent the tag from being applied (by returning a non-zero value).
For example, you could write a script that allows tags starting with
"RELEASE" to be added but not moved or deleted.
