It implies that VP9 is not widely used. We spent large amounts of engineering time on optimising HEVC.
While that could be done for VP9 it would benefit almost no one. Whereas spending the time on, say 10-bit HEVC would benefit many more users.

There is also a big technical issue with VP9. With standard encode settings the arithmetic decode of a frame is dependent on the arithmetic decode of the previous frame.
That means that multithreaded decode is very limited compared with HEVC, where we can be decoding a number of different frames concurrently.
A multi-core software decoder will always be more capable with HEVC than with VP9 (when both codecs use the default settings of encoder).
