However you label it (/8s that can grow into a /6, or /6s that can be shrunk
into /7s, if needed) doesn't make a real difference.

The important thing about the "/6 approach" is that the initial /12s
(growing to /8s) are allocated with so much room in between that you
*can* grow to a /7 or /6, if necessary, and don't have to start a
second (or even more) block per RIR.
