The thing is: inter-widget communication is off the table for v1. I
believe that we do need to say something about multiple instances,
that is along the lines of: a widget available inside a given UA
always has the same opaque globally unique identifier, and needs to
retain the same across invocations so that origin-based decisions
work. If multiple instances of the same widget are launched
simultaneously, then they all have the same opaque globally unique
identifier. It is up to them to differentiate one from another, if

And I think that's all we need to say.
