Different angle from the developer side: Apple's a11y API at the OS level is genuinely good. It's the WebKit-embedded-in-native gap that breaks. Shipped a Tauri app where Monaco editor lived inside WKWebView and found out the hard way that VoiceOver's `accessibilitySupport: auto` mode silently breaks backward text selections in Monaco — only setting it to "off" gave us correct selections. Which meant choosing between functional text selection or VoiceOver support, and the answer was selection.

Rock-solid in AppKit/UIKit. Falls over at the embedded-WebView seam where most modern desktop apps actually live.
