@bmorelli25 I'm loving the PR template, but there's a missing state: "This PR is a port" (not sure that's the best wording, but saying "The concepts in this PR only apply to one doc set (serverless or stateful)" isn't correct if the PR is a port from one doc set to another.

@dedemorton @bmorelli25 I wonder if we just add a comment that instructs the author to delete the template and just add a comment with a link for ports: "This is a port of #". Then there is a single source of truth for info about the changes -- the initial PR that is being ported.
