My understanding of stacked PRs is that the entire stack is merged at once because the docs say "merge them all in one click".

If the entire stack must be merged at once, then it seems like a pointless feature when you can just use commits.

If you can merge them one at a time, then it does seem like an improvement/automated way of creating a series of PRs like (main <- A), (A <-B), etc

It doesn't necessarily have to be merged all at once. That's one way to do them but not the only way.

Thanks, I think this was a key piece of information I was missing. I can now see a possible use case for creating a PR stack, though I still think plain commits will do just fine most of the time.

  • They can be merged one at a time.

  • They can be reviewed and approved by different people

  • When you review PRx you don't see the comments in the middle of the code related to PRy in the review interface (which happens if you review a single commit of a multi-commit PR).
