As far as I understand it's not Full RBF in itself that being debated it's also whether or not Bitcoin Core should be used to nudge or influence whether it's on or off. The best thing that could happen imo is full rbf became a standard mempool policy without bitcoin core doing a "force majure" because that is more in line with the voluntary nature of bitcoin and Bitcoin Core so far. So would it be ok this one time, for Bitcoin Core to break some functionality that some people rely on in favor of full rbf which some argue would give a more consistent user experience in the long term?
