They are. It's a step in the right direction and I absolutely welcome it.
However, it's way overdue in my book, and the harm is im the waiting. It's much better to strike while the iron's still hot and avoid these issues. As is not waiting on improving accessibility.
I'm also intrigued by the fact Google makes such custom devices for the market. I think I came across some explanations lurking (and sometimes popping my head out and commenting) here on Lemmy (and on Reddit before the API apocalypse), but I don't really have anywhere to point you in your search other than Libredirect+Reddit since searching Lemmy has always proven an uncatchable golden goose to me.
