That's a good point.
In fact, we are looking for a scalable and efficient (exterior) routing
scheme. Given that in the future there will be MANY ISPs worldwide
the vast amount of associations of provider-based prefixes to ASes
might impose a problem to the size of the routing tables.
So, there is some need to aggregate routes to providers.
Having regional prefixes is one option.

Yes, be prepared :-)
