I honestly doubt that the low hanging fruits in terms of productivity hide in these kind of things. I'm pretty sure there are about half a dozen obvious things you could do to drastically optimize your commit output (if that's what you're shooting for) before these tweaks become viable. EDIT: however I agree on the first point you made. You can't improve something you don't measure. I'm merely pointing at the fact that as of now most tools/products in this space provide nothing actionable beyond the obvious.
