I think we can add wording that says that these criteria are
useful while trying to decide whether a package should be made
Essential or not. Once it is Essential, then all bets are off, and
packages are, in effect, never removed from the set, unless
extraordinary effort is undertaken by someone.

No, this decision should remain with the ftp-masters, not hard
coded into policy.
