Thanks to @Martijn @Leonard for raising this question This is also something I have been worried about, that is, the issue of code copyright ownership and cooperation. That's why I mark FLIP-202 [1] as draft. I have sent a private email inviting the author to participate. If there is more news, I will synchronize it in time. I believe that through hard work, we will definitely win opportunities for cooperation.
