Yes, what is your point? My point is there are transactions being sent directly to miners bypassing the mempool, and that is a danger to bitcoin. Either way, using OP_RETURN will be made easier - do you want it to be made easier because miners collaborate to build a cloud API for wallets to submit transactions directly to them? Markets work. People that submit monkey jpeg transactions are not going to switch to OP_RETURN and pay 4x more just because they can.
