Why not this?
Registrars only accept to create a glue record if there already exists a PTR entry for the requested address that points to the right name.

off the top of my head, I'd say a) DNS is very spoofable b) there's a catch-22; for sensible management, most LIR's create reverse delegations at RIPE using the FQHN of their nameservers. Without the host-record glue already in place, resolvers won't be able to find that PTR record. c) not everyone wants the reverse to match the forward (is this an RFC violation? I hope not :)). d) this doesn't help the original problem where outdated glue blocks the creation of correct glue. J
