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d) this doesn't help the original problem where outdated glue blocks the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.
