[whatwg] Removing versioning from HTML

Versioning is a larger topic recently:
I wonder whether there could be a consistent pattern through all the specs from WHATWG and W3C to handle versions.
The issues and use cases are very similar if not the same everywhere.

I wholeheartedly agree with all the reasoning, but there are issues.
From an implementor's point of view it is much harder to implement and
keep up with a mutating specification. During implementation a stable spec
So versioning will allow an implementor to decide to implement the latest
stable version of some spec, while work proceeds on a newer one.
And when I refer mutating specification I'm not referring to the whole
html5 spec, but each separate component, like web storage, web workers,
Currently, because specs are being edited and might take a while to get to
CR, we have different implementors implement different parts of the
specifications, and then meanwhile the specification mutates and
implementors have to waste time updating their implementation which could
have been right from the start. I understand that implementation feedback
is necessary, but this is not very optimal.
After a spec gets to CR it can't just mutate out of thin air, hence
forking it into a new version is the way to go.
Example: Gecko, Webkit and IE have localStorage, but the spec changed a
few days ago to allow structured storage.
