Cannot determine Either the input type date field is empty or ot because there are just two states to check ( true or false ) and both empty and invalid dates have the same value.

This is a blocker for us who uses the input validation on key events.

Additional,

We cannot check either if all segments in the input type date ( year, month. day ) are empty or not, or the whole value is being inputted because of the default result which is "false" if ever the date is invalid.

Discussed at May 10 Editor's F2F: Incubate first.

Closing here as this needs incubation and therefore should be raised in the WICG https://discourse.wicg.io/
