Hi,
well, we probably could, the question is whether we will or not. I can tell you that as far as I know, plans for the near future don't contain this, unfortunately. Maybe more requests here on the forum might help to change them, but no promises.
And as Jan said, it's quite tricky and non-experienced users of rooted devices might end up breaking the whole device (if they start removing permissions from system apps for example).
