I will say, I love the idea of re-thinking PR's in the age of AI. I think it will be needed and I don't see GitHub pulling it off. I think they will just double down on trying to get AI to review it for us.

I haven't signed up, but I'm not convinced the stacked PR's is a good route. This is mostly because I'm thinking about it in terms of how I work now, so maybe after a trial run I would see it differently. My experience with launching software is people don't want to change their workflows.

So the way I imagine how this would get used by real accounts is they will still review individual PR's and merge them in like normal and avoid doing stacked PR's because a lot of us mostly care about the final result and less about the how you got there.

That is until we need to understand the how lol So being able to visualize this is probably a very useful tool for retroactive inspection over being part of the PR review workflow.

I hope the author doesn't feel like I'm dunking on them, I really love the idea of re-thinking PR.
