Then why does CSW say they need to keep scaling until they get to no limit?
Uncapping the block size is not controversial to any miner who is committed to ABC long-term. Keeping the block size capped so that we can "scale" IS controversial to a lot of miners.
I'm not 100% sure but I think there needs to be a bit of a code re-write to get it completely off. Could also be an excuse for one more hardfork to get the last of the old opcodes back
