While not really disagreeing with Leslie and Olaf, I would point out that the IPR WG was chartered to look at IETF documents. We can have a meta-discussion about where the clarifications belong, but it seems to me that the WG consensus definitely assumed that scope and no wider scope. I'd be happy

The key issue here is whether people who rely on are likely to achieve their desired result. Today it does not matter because anyone who relies on alone with no A fallback is going to receive almost no mail. That in turn is going to depend on whether software implementations are written

You are completely incorrect in describing MX records as no more than an optimization. The MX record defines the mail SERVICE. An A or record defines a HOST. Nor am I rewriting history here, the early RFCs that describe the emergence of the mail service and the DNS make it very clear that
