Should the NSAccessibility scroll-bar API be included in mapping for scrollbar role?
NSAccessibility has API (old and new) through which an AT can obtain the scrollbars associated with a scrollview. While ARIA lacks a "scrollview" role, the spec states:
Authors MUST set the aria-controls attribute on the scrollbar element to reference the scrollable area it controls.
If authors do that, then user agents could implement NSAccessibility's scroll-bar API exposing the scrollbars on the controlled element.
My question is: Should user agents do this implementation, or was it deliberately left out of the spec?
@cookiecrook: Your/Apple's input would be much appreciated. Thanks in advance!

Yes.

No. Not intentional. Thanks.
And UAs can do that for any natively scrolling views like the main web view or any overflow scroll areas.
