When you write "hosts'" do you mean that you need to configure
each individual host's routing information *separately*?

If the answer is yes, what is the reason use case for needing to configure
each host separately?

If the answer is no, why can't RA/RIO (RFC 4191) be used?

Precise answers to these questions will help to make progress
in the IETF discussion on this over the next few days.
