Sure, I just think that "merging one by one" defeats the purpose of stacked PRs even if you don't need re-approval. You can already avoid re-approval today without needing re-approval if you're not rebasing (which is not what I'd expect you mean by "regular merging"; it sounds like you mean just having a merge commit) by just not clicking merge until the other PR merges first, and at that point. That's what I meant by it sounding like all this offers is an icon telling you whether that other one already merged or not.
