Thank you for this information. I forgot that RBF opt-out was hacked on top of `nSequence`, and relative timelocks were also hacked on top of `nSequence`. In particular coins locked on mainchain for the purpose of staking a sidechain (mainstake) have to be locked with an `OP_CSV`, which immediately enables this protection.
