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.
