That's fine for me :)

Well, you wouldn't need any special cases for vCards on the server  
any more. Just implement PEP, and you're done for 90% of the non- 
messaging stuff used for IM.
If the client doesn't announce that it'd like to get notified of  
changes to that PEP node, it wouldn't receive unnecessary data, but  
could still request the info explicitly, which is right how vCards  
work right now.
