Great that AI seemingly revives the stalled PR / review space. I just hope that human and local workflows will not be an afterthought or even made harder by these tools. Its also a great chance for stacked PRs and jujutsu to shake up the market.
If you're interested in Stack PRs, you should definitely check them out on Mrge. By the way, we natively support them (in beta atm): https://docs.mrge.io/ai-review/overview
