To offer a bit of hope, both the quality and amount of information available nowadays regarding accessibility is at an all-time high.

I remember comments from people who would downplay the difficulty of getting accessibility right despite the changing landscape of web development. Part of it was that web standards hadn't fully caught up in capabilities. But another part of it was just that there wasn't that much conscious effort from the open source community to treat accessibility as a priority.

Right now you can find really high quality packages with any kind of widget without sacrificing accessibility.
