> Screen reader users do not need to open or close menus.

Are you sure about that? I’m not an expert but I was under the impression that many screen reader users use the screen reader (among other tools) to interact with the visual representation of the user interface. Not all screen reader users are 100% blind (or at least that’s what I’ve been told), and actually use a variety of zooming, high contrast, magnifying glass, etc. and a screen reader.

If my impression is correct, then many screen reader user indeed open or close menus, and they are in the way (especially when zoom levels are pumped way up), and visually hiding them by default does offer a ton of usability benefits.
