True.
My basic aim here was to make things more legible when i was putting a
limit on power8 since it was too cluttered already with a single depends
being 300 characters wide - hardly legible and very prone to
mistakes/redundancy.
I think we can commit this and "upgrade it" so to speak when Mischa's
patchset is in to clean it up more.
