This is the response I posted to the bugzilla issue: I would like to see a better motivation present for why this change is important. In particular, it is a deviation from the ECMAScript standard. While syntactic extensions to the Date.parse syntax is allowed by the specification. It is not particularly a good idea. In particular, every time a specific implementation adds such a non-standard extension, it creates a potential cross-browser interoperability hazard.
Apparently these extensions are not motivated by a desire to improve interoperability as reference [1] shows that none of Firefox, IE, and Safari currently provide these extensions. Chrome apparently does (and also Opera??). Finally, I don't understand why a WhatWG document is being used to justify a change to an ECMAScript specified function or why the WhatWG is messing with an ECMA specification. If there is a serious proposal to change the ECMAScript specification it should be brought to TC39 as a proposal where it would be given serious consideration. But simply bypassing the standards process doesn't seem like a very good idea. In particular, Google is a member of TC39 and Chrome has apparently implemented these extensions. Yet as far as I know, they have not made a proposal for this extension to TC39. Why not?
