You are looking at a problem from developer's perspective. From infrastructure perspective, it is a terrible pattern if you own the feature-flow or review app flow. It is really wasteful with no guarantee that when all the features that are written concurrently are merged, it your feature will still work as expected.

Let me put it in another way, would it have been if you would have kept, development, test, staging and production environments up to date all the time and had meaningful integration tests?
