So I'm a bit worried that 3rd party accessible apps peek at the

3rd party apps that use the accessibility APIs have no ability to
peak at the NSView hierarchy. They only see the accessibility
hierarchy you present. So if you've taken (enough) control over
what NSApp presents they'll only see what you want them to see.
Unfortunately, since we're (at least aiming to be) an embeddable
NSView, I can't have any control over the NSWindow or the NSApp. All
I can control is the topmost NSView, and everything below it. Is that
sufficient?
