I made more arguments for changing it in the next patch (D7827 <https://phab.mercurial-scm.org/D7827>). See if those can convince you :)
I'm not sure what you mean about not having correct conflicts. Related to that, I think it's actually weird (with how it's currently done) how you would not see any changes made between the merge base and the rebase base. So if there had been commits between `A` and `C` here and we were rebasing from `C`, we would not see those changes in the working copy. That's of course correct, but the dirstate's two parents suggest, IMO, that we're merging the two commits, so we should see those changes.
I can see the value in having the thing you're grafting in as a working copy parent because it makes it appear in the `hg log` output as a reminder. However, I don't think that's what the purpose of the dirstate parent should be. We could perhaps add another mechanism for showing the commit that's being rebased, and maybe also the base (which is generally not the merge base).
