Should indeed not be a surprise given the spec's quality. I mean, it's
basically a copy-paste of their reference decoder in a different
order. No wonder they forgot half of it.

More constructively, I think all things that distinguish subversions
(libvpx name) / profiles (David's name for the same thing) are missing
from the spec, so we sort of go by them as we find them.
