I said require all scrptPubkeys to have op_maturity/rcltv/csv 100+, but
yeah, that would work.
Regarding nKillTime, please call it nExpiryTime. And instead of fill or
kill transactions, ttansactions that expire. It is not only more accurate
(ie fill or kill is for market orders that complete in their full amount
now or are cancelled, not for transfers) and it is the term we have been
using for years.
Reinventing the wheel by changing its name it's something we do often (for
example, rcltv was op_maturity in February 2014 and was "reinvented" as
rcltv recently. This makes it harder for people to learn and follow up.
Please don't insist in fok, that's for market orders and works differently
than expiries. Expiry is the old name and it's also much more accurate.
