welcome to v6. we forgot to sort out routing, so just don't do it. you're kidding, right?

No, I'm not kidding but maybe we're talking about a different thing (you may have a more generalized network in mind).

The way I see it, a network which is considering "Juniper M7i or Cisco 7300 plus a couple of switches" as an option does not _need_ 220K IPv4 routes in its routing table. Whether it has 150K, 40K (Hi Simon!) or 5K shouldn't matter that much from the functionality perspective.

If we still disagree, it might be interesting to hear why filtered BGP feeds from upstream and appropriately placed default routes to cover the holes wouldn't provide a functionally and operationally an equivalent solution?
