_s is fairly solid when it comes to accessibility basics, and meets most of the accessibility-ready requirements. Some, like color contrast, we can't meet because _s is a starter theme that we never know what will become of it until someone makes something awesome.

The last big piece that could be better is headings. We have a long-open pull request for it that we need to work on as a community. Of course, I bet we can find more ways to improve its accessibility. As Ian mentioned below, we welcome newcomers and pull requests.
