RFC: We use the RFC (Request for Comments) mechanism to discuss and organize some of the more advanced and self-contained features. These are the projects that we would like to work on but still lack a concrete design or implementation roadmap for because of their complexity. We document these requests and the threaded proposals in the hope that we could provide the community with a good enough context and draw upon insights from the potentially passionate minds. You can find all the ongoing RFCs here, and you are also welcome to file new RFCs with us!
