False. Is the spec not clear on this?

You can already do this reasonably easily; I'm not sure an explicit API is
really that useful. I'll bear it in mind though.

That's just a UI detail. Nothing is stopping UA implementors from
including this kind of UI today.

No, negative years aren't allowed. As has been pointed out by others, the
date control isn't really that useful as defined today for
non-contemporary dates. The use case is primarily e-commerce. Historical
cases are far more complex, rarer, and probably need custom UI, and thus
don't really fall in our "80%" target.
Let us know if there's anything else we can do to help with your
implementation! Also, note that there's an implementors mailing list if
you want to discuss implementation-specific details:
