As I mentioned in my email sent at some time prior to your mail (though it may not have hit your inbox in time, I'm not sure), yes, I had misunderstood the specifics of the P2MR proposal. I apologize and there was no intent to straw-man here. As I mention in that email, as well as the one I just sent to ethan, however, I still see zero reason to prefer it over a P2TR(v2) approach. It seems strictly inferior. Matt -- You received this message because you are subscribed to the Google Groups "Bitcoin Development Mailing List" group.
