Will KMS change the magic formula?

Announcing thinking is still announcing, since it was published. Also that's not the sort of thing a developer would bring up unless they at least had a plan of action.

I do think they will be changing it, but we can't be sure. They're probably exploring the formula as an option, but they might not actually impliment it if it doesn't work out. I think it does work out well, so I have high hopes.
