Rejoice, finally a new feature that isn't AI related.
I get your point, but it kind of is AI related. The size of PRs since AI has made it much harder to review a diff. Stacking the PRs seems like a response to this problem.
Not AI related, but I plan on having my agents use this heavily so I can review PRs in bite-sized chunks instead of all at once.
This is definitely connected to AI. High code volume, bigger PRs.
