That appears to be the permanent fate of the World Wide Web Consortium and its specs, unfortunately.
Whatsmore, the original intention of the W3C wasn't as a dictator to companies as to what to implement - the use of the term "recommendation" rather than "standard" is very much deliberate.
In any open platform, the fact that vendors are willing to follow specifications created by a standards body is the only thing that makes them relevant, whether the W3C or otherwise. There's no way to force people to implement a specification fully and correctly.
