Agreed... That's why I'm trying to make life better on both fronts.

One one hand, I'm working on a proposal for IETF that would, I think, allow
incremental and beneficial steps towards separatin.

On the other hand, I put forth this policy proposal in the hopes of making
it possible to prevent a ULA land rush for routing table entries.
