Some "frameworks" put a ton of work into accessibility.

The Polymer team's entire element catalog is accessible with ARIA integration done with assistance from Chrome's dedicated accessibility engineers. We even provide reusable abstractions that make writing your own accessible elements easier, like iron-a11y-announcer and iron-a11y-keys.

Accessibility was a big topic at our last Polymer Summit: https://www.youtube.com/watch?v=o6yLWihykVA

Thanks for the link - was really interesting, particularly the introduction which explains why accessibility is so important and the number of people that it touches.
