The current draft is not really in a good shape, still a lot of
"proprietary" stuff and complexity that has the get out.

It also will allow us with an easy way to access link layer metrics,
even from radios we can only reach over ethernet.

Yes, it is... it might become a good raw data source for the metric
calculation of any kind of mesh routing protocol.
