Oh I see what you mean, in addition to the data being encrypted.

I'll have to see how Wireguard does this, but I remember reading from
Jason that he was not happy with the way he integrated Noise with UDP.
Or maybe I misread him? It'd be nice to have a spec to formalize how
people can do it anyway.

I'll think more about this, but I definitely want the in-order part of
Strobe in the Disco spec (if not the default part) since this is what
I want to implement (and for the moment I'm the main user of the Disco
spec).
