Making replacability turn on _after_ an expiry time is reached has been
suggested before, IIRC by Matt Corallo. However I believe the approach of
enabling full-rbf _until_ a time is reached is clever and novel.

I'd suggest doing both at once. Long-running txs are certainly useful. But if a
tx hasn't been mined in a few blocks, it certainly can't be relied on for
zeroconf.
