Hopefully this starts supporting accessibility tools before it gets too much traction and people start shipping inaccessible apps. The WebAssembley output demos on the homepage just render to a and are completely inaccessible with any of the usual tools (screen reader, keyboard-only, voice dictation etc) but there's a GitHub issue ( https://github.com/slint-ui/slint/issues/32 ) so fingers crossed.
* Flutter has no accessibility bindings on the web and therefore falls under the same “illegal” category.
