What I don't understand is, if contiguous, illegal content is the major concern here, why not exclusively focus on capping OP_RETURN and going for the kill? Why mixing it with additional restrictions that are addressing a different, less pressing issue, and that will objectively cause the whole thing to fail, when you had a clear shot at getting the high priority issue fixed?

Also, we've been aware of this attack vector for so many years? Why is it suddenly an emergency now, when even the press has been talking about it for at least a decade & contiguous illegal content could have been posted on chain anytime by a well organized adversary?

Finally, why pretending it's just reversing what core v30 did, when you can't ignore this bip is doing much more than that?
