Does that really apply to presence. The client just sends a
<presence></presence> packet to the server. The server decides who to
send it to.
Doesn't it?

If clients apply nodeprep themselves, then they'll figure it out.  If
they don't, they'll just silently drop the stanza.  The RFC says the
SHOULD apply nodeprep, (while the server MUST) which means they're free
to assume it's already kosher if they choose. :/
