I didn’t say it was easy, but what I listed are to me the best ways to reduce as much friction as possible.

AsI recall, Microsoft wanted devs using their proprietary silverlight and c# which required a complete rewrite from iOS or Android. Allowing existing apps to bundle their preferred Android runtime is a lot closer to something like containers or flatpak and is a proven way to reduce developer friction. Ironically, such an app running in wasm would be supported indefinitely while Android apps on Android eventually lose support.
