> I think the point the GP was trying to make is that the GitHub UI ought to be able to allow you to submit a branch with multiple well-organized commits and review each commit separately with its own PR.

That's what this feature is, conceptually. In practice, it does seem slightly more cumbersome due to the fact that they're building it on top of the existing, branch-based PR system, but if you want to keep it to one commit, you can (and that's how I've been working with PRs for a while now regardless, honestly).

They confirmed in other comments here that you don't have to use the CLI, just like you don't have to use gh in general to make pull requests, it's just that they think the experience is nicer with it. This is largely a forge-side UI change.
