It's hard to argue with that logic.
If nLockTime is used for expiration, transaction creator can't lie to
help tx live longer without pushing initial confirmation eligibility
into the future. Very pretty. It would also enable "fill or kill"
transactions with a backdated nLockTime, which must be confirmed in a
few blocks, or start vanishing from mempools.
