Reading that post sent me down the path to this one. This stack order makes total sense, although in practice it's possible 1-2 merge into a single product with two distinct steps.

The 3. is interesting too - my suspicion is that ~70% of PRs are too minor to need human review as the models get better, but the top 30% will because there will be opinion on what is and isn't the right way to do that complex change.
