I think a lot of confusion and coding errors bound to happen in either
case. I easily can see non-global IDs that appears as global because
implementations "forget" to set the bit on (actually, the opposite error
would be less problematic). The future protocols that want to take
advantage of the "u" bit are better be prepared to deal with this.
Therefore I'd vote to do what is more convenient and sensible with what we
already have.
