Thanks for pointing it out. Frankly I haven't looked at that topic with Fyne yet. If I google it I see this response from the main Fyne maintainer from 2022:
On that thread, I plugged my AccessKit project (https://accesskit.dev/). We have a C API now, and the project is much further along than when I commented on that old thread, so somebody could develop Go bindings now.
What an excellent project and idea. Accessibility is always a big gap in these cross-platform, lowest common denominator frameworks, glad to see someone is trying to tackle it.

They do keep actively moving forward so I have hope this will get addressed.
