<input type="date">: not marked at risk

Hello,

I've just found that the current HTML5 CR draft lists all dates-and-time
related input types as "at risk", except the "date" type.
http://www.w3.org/TR/2013/CR-html5-20130806/#status-of-this-document

Is that an oversight, or is there any reason not to mark this particular
type as at risk?

Thanks,
