Do resolvers these days actually use more then 8GB of RAM? Because a 1000 euro
1U server comes with 8GB and a quadcore cpu.

Mind you that you're just changing the time stamp of the old->new record change.
While you can argue about helping bad administrators getting rid of bad long TTL
records, you can also reason the other way where a bad administrator's mistake
will show up sooner before he corrects it. I think in general, one should not base
an architecture on such a corner case.
