Agreed, but why do we need to save space? It would be possible to
have the data structure that stores the delete RR point to the RR
that’s to be deleted, so if on-disk or in-memory efficiency is really
important, this would address that. In practice, though, this
option isn’t likely to be in use on servers, like large ISP caches,
where space is at a premium. So this seems like a false economy.
+1. again, this is how DEFUPD worked in 1996, and for this reason.
