Users of opam-repo: what sort of change tracking would you like?

Dear users (of the opam-repository in particular, but also of the container images and various other pieces of infrastructure that we publish from,

After that mouthful of an intro, just a brief note to solicit opinions over at ocaml/infrastructure#20 on what would be most useful to users of the opam-repo on what sort of change tracking would be most useful for you to find out what’s breaking (or has been fixed) as the live infrastructure evolves.

There’s a lot of improvements going in thanks to all the contributions to the various CIs, and your inputs on that issue, or this thread, would be welcome.
