IETF is probably hyperbole, but it's a valid concern. Publishing an open standard leaves you vulnerable to people expecting you to support it, especially in terms of backwards compatibility. If Google is agile and pushes a new version of the standard (obviously supported by their infrastructure) weekly that breaks backwards compatibility (which they can do because they control the entire ecosystem), they will be criticized for not taking openness serious, because competing implementations will always be playing catch-up and thus never become a viable competitor. A completely good faith (and perhaps naive) read on the situation is that they need to settle the protocol to the point where they can commit to some level of good faith long term support and giving proper notice of breaking changes, then they'll release it.
