Another option after 3.0.3 is to allow grant tables to support these large
mappings. I have some ideas how to do this fairly efficiently, given that
it'll be okay to track mappings to all the pages as an aggregate. It's not
going to happen for now though -- it'll just be a shame if we add
grant-table support later that it'll change the setup protocol. However, we
can probably maintain backward compatibility if we think about it a bit.
