Yes, please do.  I think this is a good discussion for PF to have.  It's possible these roles should be added.

I think datepicker would be much better, but that role doesn't seem to exist in aria.  And I have certainly used interfaces that required me to pick a date by hitting the little "arrow" glyph way too often.

How would you recommend AT represent these input types?  As text fields with validity patterns?

Is the (aria-)role supposed to represent the physical implementation that happens to have been chosen, or the underlying semantics?

Should the AT see the same underlying date field differently depending on which browser is being used (and how that browser vendor decided to style the chooser for sighted users)?
