My understandimg of Polylith so far, in the context of "untangling development and production" is that you might put together components and bases differently in dev vs prod. If that's correct, untangling development and production seems to run counter to the idea of trying to match development and production as closely as possible (eg with containers to mimic environments better) to make testing more accurate/realistic. Based on my very limited experience, I don't really understand why you would want to drop dev/prod parity entirely.
Having said that, I'm sure it's possible to run the prod version(s) locally and test them, but then don't you lose the benefits of separating deployment complexity from development complexity since you're now running the prod version locally anyways?
