In the future I bet they have software which will automatically scan and 
implement any specification ;).

That said, as long as ‘don’t break the web’ remains a fundamental 
principle of HTML5, I don’t see a direct need for versioning. If any 
future version of HTML decides to ditch that principle, versioning can 
be re-introduced. Worst case, any implementation can create a custom 
attribute on the root element to indicate which ‘rendering-mode’ has to 
be used. This is more likely to be effective than a 
specification-version, as the problems that supposedly need different 
rendering modes are related to the releases of the software and not the 
specification.
