It's not just about touch vs mouse/keyboard, it's the whole interaction design philosophy.
And it's not as if you can say that getting the Android developer experience on desktop is going to entice developers. Compose is decent, but the actual Android system APIs make Win32 look brilliant. At least Win32 is stable.
For this to be viable, there has to be a bigger strategy than just "Android apps and APIs on a desktop" -- because neither of those are appealing.
Users and developers will just stick with the web.
