No disrespect intended to Ronald Bultje and his prolific work for free
software, but he worked for Google on libvpx for more than two years as
they developed VP9 ([e-mail] has >580 commits between April 2011
and July 2013) and "was one of the people involved in creating" VP9 in the
first place, as he wrote on that blog post. I don't think ffvp9 really
counts for what you want to see in a well-specified format.
