It's just kinda funny that nodes think they can control what miners put in a block template. Or that they can stop valid transactions from propagating across mempools to miners. Cause they sure as hell won't reject a valid block containing big op returns. It's like Bitcoin devs can only spark controversy to remain relevant nowadays.
