Also, even if they did use native widgets that come with integrated accessibility features, would those actually work as intended for a multi user collaborative editor like Zed? Imagine a group of four people live collaborating on a file in Zed. How do you present the actions that are being taken by everyone so that a screen reader can understand what is going on? Mute everyone except the user? Speak every keystroke pressed by everyone all of the time? Announce line changes made by others when they pause for a while / when they move to another line? In short, I think if accessibility for screen readers were to happen for Zed it would take a monumental amount of effort to make it usable, regardless of whether they are using native widgets or not.
