I think it is a good idea. JavaScripts and CSS can enhance it but should not be required.

Accessibility functions are also helpful; if designed well then it would be helpful for everyone (not only if you are blind or other disabilities), in many possible circumstances.

I have a theory that "accessibility" is just a euphemism for "usability", when it's so bat that a noticeable portion of your userbase is locked out.
