You are fighting the wrong fight. People want choices not dictates. There is no good reason to have unlimited OP_Return. The only people benefiting from this are the miners and NO, just because there are already workarounds doesn’t justify removing it. A lot of people don’t want more spam and CSAM. Just give them an option to keep the limit in the next release, then everyone would be happy. If not, people will just fork off or remove that code and rebuild it anyways.
