Unlike what people reply here out of ignorance, your thinking is correct, meaning, that Google has already done the hard work to create a TRULY modern OS, with proper usability, security, and yes, a way better compositor than wayland (in fact, android has the best compositor in the world, compared to ANY OS). A properly modified desktop OS based on it (better than Samsung’s DeX for example), that is also able to run normal Linux apps, would be a huge winner.
Wayland is not as advanced as android’s system, so i don’t see why not use android’s. The license for it is fine.
