I'm OK with adoption.  

That said, I believe that this falls a long way short of addressing the attacks that I'm aware of.  But that assumes we share an understanding about what those attacks are.  To begin with, we probably need a clearer description of goals.  

To give an idea, address validation in QUIC is much more complex than is proposed here, for reasons I believe to be good.  If this document does less than QUIC, it needs to justify that.
