I apologize for saying your use case is incorrect-- clearly, someone using a screen reader would have a totally legit if still comparatively uncommon use case. I have used the modern web in screen readers because I've developed modern web pages to be accessible, which by my estimation means doing more than using a WCAG scanner.

I still think it's ridiculous to say that developers are doing something wrong by using modern practices just because it doesn't fit your use case. You can have your opinion all you want to and I can have my opinion about it.
