Some disable, for reasons of privacy or scalability.
Many do respond to probes with the last offline status.

No, actually - one of the nice things about XMPP is that quite often,
your contacts get the functionalty of your server. So if you use a
server that does provide offline status - like, say, jabber.org -
then your contacts will see that information if their client is
capable, even if their own server isn't.
It's the same for PEP - your contacts will see your PEP information
if their client requests it, no matter if their server doesn't.
So if you want this behaviour, use a server that supports it. And if
you want this behaviour for your contacts, encourage them to change
implementation or service to one that does.
