Unless there is another mechanism for a record to die, it'll still be important to have a TTL.

TTLs could be kept quite long, though, since they'd only be used when push updates are not occurring.

They'd also be used by any clients that don't understand DNS push notifications. That's including a lot of networking hardware, industrial hardware, medical devices, etc.
