My hypothesis is that CSW and team wanted the SV transactions to be replayable on BCH, because they believed there would not be a split. If there was no split, the SV transactions would not have confirmed without having removed the replay protection. And so they intentionally removed the replay protection.
But CSW doesn't understand how mining works. The chains did split because the rulesets were mutually incompatible (that this would happen was obvious). Once it was obvious that there were indeed two chains, then replay protection became important and CSW and team now want it back.
Readers should go through Calvin Ayre's tweets the last month or so. I think it is obvious that he has a completely warped vision of how bitcoin works (e.g., he wants the two chains to "re-merge" somehow). I suspect this is because he listens to CSW who also has no clue about bitcoin at the technical level.
