Yes, if it's not there already.
Btw, the simple communications blocking XEP already has a clause that
requires the server to send presence of unblocked contacts.

Right. And if you let the client do it, then you rule out the server's
possibility of doing optimizations (since it doesn't know why you are
doing a probe). Moreover, the client can't do any optimizations on
itself, because it doesn't know the privacy list logic (and it
shouldn't try to either, because the server might have its own logic
for doing that).
