Unfortunately bip-8 lockinontimeout is the protocol upgradoors wet dream because now you can speedy trial with a preset outcome unless someone does uasf. That stacks all the chips in favor of the smart contract pushing dev.

If I look at the "arguments for" covenants the other day, its basically "but some BTC is locked up by bitgo to be used on Ethereum." Its like proposing that every dollar bill needs a gambling chip in it because there's so much laying around casino vaults.
