Hi Lalita, The privacy interface is marked as "causes havoc" in the spec (and hence deprecated in libtelepathy) is because nobody has implemented it yet, so we have no idea whether it's useful or applicable to real world protocols. It's possible that when we (or someone else) did implement this, it would turn out to be wrong and would need changing.
That said, it's just used to find and set the default policy for who can see you or message you. There's actually no way to discover/change this on XMPP servers, so Gabble wouldn't implement this interface anyway. The defaults are that nobody can see your presence and that everyone can message you, except on Google where only people who can see your presence can message you. The more relevant API for blocking/unblocking people in Telepathy is adding people to the "deny" contact list. As you've noted this is only available in Gabble when connected to a Google servers using their roster extensions. This is because jabber:iq:privacy is too complicated and powerful for us to use and expose through such a simple API. If we used it in a simple way (only manipulating/activating one ACL, ignoring others) then we'd not be compatible with other clients, or if we wanted to use it in a complex way we'd need a more complicated Telepathy API. This is actually why Google didn't use it either - it's too complicated for their use case of simple blocking/unblocking. Since then, a XEP for simple blocking (http://www.xmpp.org/extensions/xep-0191.html) has been written, so if we wanted to implement blocking in Gabble for non-Google XMPP server, we'd use that.
