It is very useful for protecting role aliases (e.g. abuse, postmaster) 
that are mapped to targets (e.g. root or an off-system address) that 
should not generally be left unprotected.

It also is useful to allow end users to create ad hoc tagged addresses 
on the fly that get more lenient treatment without needing to create any 
per-address config on the server. If the tag (or in some cases, the 
whole local-part for a 1-user virtual domain) matches a specific 
pattern, it is given a pass round the insane local blacklist and a 
SpamAssassin bonus. Users can kill a particular tagged address by moving 
mail to that address into a special IMAP mailbox. This is far simpler 
than training users to manage a user_prefs file or database record.
