I assume also adapters from std::span<T> and ranges thereof, since those 
are the New Hotness?

I am a little hesitant in breaking this off from Asio, since as Klemens 
pointed out it would be unusual to not have the header available, and 
since whatever is in Asio is already somewhat-standards-adjacent with 
some third party implementations already, making them _almost_ 
vocabulary types anyway.  (Though of course "almost" compiles no code.)

(I don't know whether that makes it better or worse if your types are 
identical to the ASIO ones or "improved" in some way.)
