As things stand today, you are right - "Scope" becomes only another factor in the 
routing decision of a packet.

However, if we make it more explicit, and allow communication only among addresses at 
the same scope, I don't see it as
such a pain to hosts and apps. Address selection is not to complex (not as simple as 
"everyone have a global address",
but far simpler than what we have now).

Could you be more specific?
