That's not correct. If you read the draft, in the /128 case there is no
need for this information to be published using HNCP. You would only
publish which routers take part in the roaming.

Now, while I mostly agree that the /64 would make certain things easier,
it is not really a feasible solution unless we can ensure, that all ISPs
delegate _at least_ a /56.
