Looks nice, but like almost all promising new UI toolkits accessibility is not even mentioned.

I think everyone is waiting for AccessKit to be ready…

For those (like me) just hearing about AccessKit, I assume it's this: https://github.com/AccessKit/accesskit

Neat! I really like the Rust ethos of creating modular cross-platform adopters (e.g. winit, getrandom), and from a brief skim this seems to fit that model.
