That would turn the question from "Is Alice and LiveJournal logged in?" 
to "Which LiveJournal user is logged in?".

There's a privacy concern there, which is why you are required to ask 
for a particular user.

In theory you could split the request up into a request domain and a 
request user, but that's not really much different than a URL with both 
of those things in it.
