It does explain the reasons, but it still doesn't me 
do what I need to do:

I need to know if a JID does or does not exist when 
a user tries to add the JID to their buddy list.  If 
a user mistypes a JID, I don't want to fool the user 
into thinking that they've added a real person.

Besides, we would still be able to add people to a 
roster and not attempt to subscribe to them simply by 
omitting the ask="subscribe" attribute inside of the 
item element
