One of the top things to do about MEV is to make all transactions in a
block simultaneous, so for example if you have a price oracle it can be
limited to only reporting one price per block so although it can be
manipulated to either report a high or low price it can't simultaneously do
both. In Bitcoin ordering is strictly enforced but there's a loophole that
things which happen in the same transaction do happen simultaneously, so
future extensions could be made to only sign things they care about and are
okay with transactions getting aggregated just by smushing them together.
That of course requires a new signature opcode, because current signatures
always sign the whole transaction.
