What use is a safe API when it makes the entire system impossible to use by a significant fraction of the population (ie wayland and the visually disabled)? It's been a decade+ and none of the waylands have managed to support screen readers yet.
Are we to just throw out that whole class of people and tell them, "You don't get to use linux desktop computers anymore when X11 support is dropped". As someone with retinas that are progressively tearing apart, who already uses text to speech for many things, this is incredibly disheartening. I really don't want to have to switch to the Apple ecosystem.
