I think this is a good summary.

I will add, if the goal is to meet the requirements in the liaison letter (https://datatracker.ietf.org/liaison/1676/) in the short term, then minimizing the changes would be helpful.

If the goal is “general overlay network”, then that is going to take a lot longer, might well need a BOF and its own working group.
