Most of the platforms were successfully petitioned to have rust sdk mandatory added so that rust code can be added to the platforms. The previously situation was rust was not allowed because the external dependency of the rust sdk was blocked.

Note that the rust having no stable api is not fixed, so I think there's a bunch of internal systems on each platform to hard lock the rust dependencies across multiple rust users.

There's some friction between platform packagers and the code that the author wrote exactly as it was written.
