> They don't. But reviewing individual commits in the GitHub UI is hard.
So instead of solving that problem, GitHub developed tooling around a workaround for that problem (targeting a PR at another branch that also has a PR).
Expanding reviews to allow per-commit reviews avoids the need for managing additional branches and all the headache that comes with it.
Indeed. But lots of people have never even heard of Gerrit :P.
And the implementation feels very much like it sits in the UI layer, rather than further down the stack.
I'm not trying to claim stacking PRs in this way is the best way (it's not). But it does add an extra affordance for those who want it without burdening those who don't with the need to understand why someone would prefer it.
And there are also plenty of ways that people have been working around GitHub's (and to a lesser extent, git's) lack of tooling for working on changes in this way. I'm sure they have customers clamouring for the feature; whether they'll be happy with what they get remains to be seen.
(Very happy jujutsu user here, my tooling makes it really easy to create stacked commits with a stable identifier that maps really easily to branches and then onwards to running `gh stack`, but what GitHub have delivered is definitely still lacking)
