From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

My understanding is that AccessKit is an entirely separate thing to the portal.
Unfortunately, for several things, your choices are X, which is broken by design and few developers QA their software for anymore, or Wayland, which works pretty well in many areas, but where several important (or even basic) features are quagmired by bike shedding. But things are improving really quickly, and part of that is everyone shifting focus to Wayland.
I recently tried to navigate my GNOME desktop via screen reader and did not enjoy the experience. If I ever need it, I hope it works properly by that point...
At least for me, X is a worse experience on every computer I own (including the NVIDIA one), which is why I use Wayland. Neither is problem-free. I'm fortunate enough not to depend on accessibility features; perhaps my opinion would be different then.
