I’m torn on the specifics and we’ll have to think about the explanations. 
While the former is more clear and elegant, it would possibly require 
additional code in existing clients to make use of. A status 307 + status 333 
may do the trick for that, while not being confusing to conforming clients.

(Bonus independent of the specific approach: servers may remove a presence 
subscription from the roster when they encounter such a presence stanza.)

kind regards,
