I think this is a very good idea. Several years ago, I learned how to browse the web with a keyboard and screen reader. Honestly, picking up that skill made me a noticeably better software developer. Prior to that experience, I had a vague idea about accessibility, but for the most part, it was just about checking a box when I was going for certain types of contracts. But, once I got into the screen reader flow, all of my formerly vague ideas became really solid concepts. I build much more accessible applications now because of this knowledge.
