It's a lot to read and respond, but I will say this that I don't think i'm in favor of relaxing op_return limit. But I understand there's lot of technical nuance to this, I will let everyone make up their own mind and what has to happen will happen. For now, I'm sticking with what I already said. FWIW, my nodes as well as mining is with datacarrier=0, so of course I've a strong opinion and which is please don't spam and also atleast I am not a user of smart contract projects that are coming to Bitcoin. They upset me.
