That'd be great but I'm not feeling like the Chinese market is too worried about open development. I got a Huawei Watch 5 as a gift and I liked it enough to try to develop my own apps (their app store is a wasteland) but to my surprise Harmony OS is not Android compatible (just Android based somehow). The watch's developer mode is useless. Trying to register a developer account is almost impossible and it seems they only allow chinese nationals and there's no plan to open registration. I couldn't even download their custom IDE (something like Android Studio) without an account.

Maybe it's just my experience.
