Current policy allows for greater-than-/48 PI assignments if the org can
justify it. However, since we haven't told staff (via policy) what that
justification should look like, they are currently approving all requests
and several orgs have taken advantage of that.
So, it's entirely possible someone could get a /40 and deaggregate that into
256 routes if they wanted to. Given the entire v6 routing table is around
700 routes today, it's obviously not a problem yet :)
