Really important to have support for ARIA roles on these types of widgets. That's what they were made for, and jQueryUI does a pretty good job at this.
Accessibility is important.

What's the current status on 508/ARIA Compliance?
Rajgopal Ramani commented
Any further update on when ARIA support is planned to be released?
What is you road-map for section 508 compliance? We are thinking of licensing KendoUI at our organization.
Brandon Worrell commented
Agreed. You are cutting yourself out of usage with any government type work that requires Section 508 compliance if you aren't accessible.
