As a follow-up, I propose to reduce future contention in future requests by formalizing a written policy that is minimally subjective and easily repeatable. If this exists, I could not find it.

There is Process for aliases, auto-connections and tracks which discusses the procedure. Unlike with classic and base snaps which have formalized criteria, interface auto-connections are not codified because each request is unique and subjective and we want to maintain flexibility for change and new thought. That said, all the reviewers consider prior votes for similar requests which can be shown through forum research.
