This difference here is that anything which blocks in between will send
back a service unavailable iq error.
The way the jep is phrased - if the client chooses to 'ignore' it, it
will just silently blocked : which in itself is a presence leak since it
is a behavioural change.
Dropping iq sounds really weird to me btw.
