If you present a unified privacy interface, then the privacy settings
for some protocols will become nonsense.
In MSN you don't cannot have FT without IM, chat = IM, and you cannot
chat with somebody you cannot see online, nor send message to somebody
who has you blocked.
In short: blocked means completely blocked. You are going to make the
same mistake again: present privacy settings that are not feasible in
MSN, and thus, confuse the user.

That's not practical, that's hypothetical. I bet you don't have a user
B, nor C in your buddy list, and I haven't heard of anyone who has

I disagree, if it happens, it will be for a very few users. So you'll
add options for a few, to the detriment of the grand majority. Is
there a bug report asking for such feature, how many votes does it
have? Not only will you complicate the API and UI with such settings,
some protocols cannot honor such granularity, so you are making the
same mistake again. The original purpose of the privacy rewrite was to
present to the user realistic privacy settings; something that
actually has the expected behavior in the protocol used.
How about we concentrate on real problems instead of hypothetical ones?
