That seems like a ridiculously complex pipeline to maintain and onboard into. I personally dislike this "do it all" monorepos in most cases, there are cases were they work, but they also break a lot of other things.

I have not seen metris or blogs that prove this "uptick in build efficiency" or an increase productivity.

While I do like the idea behind bazel, I hate repeating deps in things like "go_repository" with gazelle.
