Support units in Intl.DisplayNames

For building better accessible web applications more easily it would be useful to retrieve unit names via the Intl.DisplayNames API. This is analogous to currencies, regions, languages or scripts.

Consider an input field for weights, in which the output of Intl.NumberFormat could be displayed regularly and expose "42 Kilogramm" via the accessible tree.

Which units? All of them?

I would expect the ones that are supported by NumberFormat. It is still very young and I do not know about the coverage of the different implementations, but there is a minimal, "sanctioned" set defined in ECMA 402.
