I don't believe that's true.  The UA is *not* just the core code base of the browser as distributed by the manufacturer.  The UA is the entire 'opaque box' that terminates the HTTP protocol.  A browser that allows plug-ins allows them *inside* that box;  from our point of view, the plug-ins are part of the UA, and that collection of software is responsible for making sure that they follow the rules.

We have requirements (reflecting the user intent) on what comes out of the box.  I still do not believe we need to say more.  If, like Bryan, you want to be able to make that box out of a cloud of entities co-operating over a network, then you can do that as well.
