And are you supposed to know a client named "FooBar2000" is a phone or not?
Each client should have an internal mapping of every existing client?
Specially useless if that client is mutlipaltform and work on both phone and 

Better to use the <identity type="phone"/> in the disco#info reply.

???   Old implementation are already written. And doesn't behave like that.

If you keep a different node per client, It can't be cross-client.  Only 
cross-version if you remove the version from the node, But it's still better 
than nothing
