Thanks! Sorry if I came off as brash, time has been tight recently. You've already put a lot of work into a very informative article, and it's appreciated. The outlook is solid. I'd like to find an opportunity to revisit some of my own code with your writing in mind.

Part of the reason for mentioning the radio-tabs is because I was working on my own implementation for a personal project a few weeks ago. My goal was specifically using the role="tab"/role="tabpanel" pattern, but my read of the guidance left me feeling like I was trapped with using JS to set those. Since it was timeboxed, I bailed out to augmenting it with JS for and moved on.

My hope was maybe somebody on HN with more of a background on accessibility could interject some thoughts here.
