While I agree with your sentiment, I believe there are multiple classes that
must be considered.  I don't believe that a user should be able to inject
global prefixes from a cable modem and a DSL line at home; however, I do
believe there's room for global prefixes to be injected by large,
multi-national enterprises as end-users.  I ask for caution within this
community not to condemn a solution that may be right for the very large
end-users because of a fear someone might want to apply it to home networks --
they're vastly different beasts.

I would probably organize them a bit differently, based upon the
characteristics of the multi-homed downstream/end-user networks.
