That's a FEATURE, not a "problem". Makes it inexcusable not to keep up with specs (same design built into HTML5, SVG, etc.).  

See also how this de-cupling worked for XML:

I don't see how that is possible: if your spec does not conform to /latest/, then you are non-conforming. If you were conforming yesterday, but a new version of the a spec comes out tomorrow, then you update your software to conform to the latest version. As an example, almost all Browsers are on a 6 week release cycle now: so it's quite inexcusable to expect to just conform to some dates draft and then expected to never have to update the software (i.e., conformance is an ongoing "living process": specs are buggy, tests are buggy, and software is buggy… any of those can affect an conformance over time: the are all living things).  

Pretending that slapping a date on spec means anything is unhelpful (and actually harmful, because all specs contain bugs and hence must be continuously maintained).
