From HTML WG Wiki
No Change to Status Section
Written by Philip Jägenstedt.
Leave the status section up to the discretion of the editor and W3C staff.
WHATWG's contributions to the development of HTML5 are substantial, to say the least. Acknowledging its existence, briefly explaining its relationship to the W3C and linking to several useful resources hosted by the WHATWG is the least that the W3C could to.
With the WHATWG having dropped the "5" from HTML5, the risk of confusion is lower than ever. More importantly, lacking evidence of actual confusion, acting pre-emptively because there might be confusion is a waste of everyone's time.
No spec change.
Attentive readers of the spec will learn something about how the spec is developed and the options they have for giving feedback.
The WG will have wasted time on this non-issue ISSUE.
