The latter. And I really prefer to have this explicit over deriving the priority from the registration order. That's way too fragile/unhandy. If you decide to replace a region of lower priority later on, you need to reregister everything at that level.Exactly.
So priority is equivalent to registration order except it's explicit?So this is more palatable to me but I do prefer registration order since it promises less.
But that said, this is a relatively minor feature IMHO given that I now understand the scope so I'm not going to object strongly.
