All the more reason for simply letting page authors define any fields they need using the existing input primitives like "number". I think putting the onus for this sort of investigation on the UA will simply mean this won't get implemented.

Is any of this discussion being had for the existing date type? The existing spec simply says a year must be "Four or more digits, representing year, where year > 0".

I think all of this is important discussion not explicitly related to the need for a new input of type "year". The question we need to identify is whether there's additional value (semantic or otherwise) in defining input type="year" distinctly from a textual/numeric input with name="year". The precise behaviour of any such field is surely dependent on an agreement that its existence is valuable.
