X11 never had a model to permit this for accessibility tooling while blocking it for other code. Wayland does, but suffers from the surrounding infrastructure not being well developed yet.
Does it? Because last I checked, Wayland did not, in fact, have the same features, and you don't get credit for "permitting" use of something that doesn't exist.
When you read anything about Linux accessibility, ask yourself whether you're reading something written by either a user of the accessibility features, or a developer of them. If they're neither, ask yourself why they actually care and what they're doing to make the future better.
Okay: AFAIK, mjg59 is not a user of a11y features, and is not a developer of them (22 years ago yes, since then no). Ergo, by his own standards he isn't allowed to talk about this.
