Google for "timers versus triggers". We had that discussion years ago.
It ended up in a stalemate and we continued on the bases that we should
put the message in the zone because there was no agreement on how or
whom should do the work when. By putting the data in the, a zone reload
can trigger a push, and a parent can do a check based on its own timers.

Additionally, any other type of trigger signaling needs some new port
that's not port 53 or some parental server that is not the production
TLD server to answer to the trigger. TLDs weren't willing to do either.

So I disagree. We do not need a new signaling mechanism.
