Is rust in Linux a good opportunity to review the Linux licensing? For example, go Gplv2+ instead of just GPLv2? Or maybe just forcing developers to subscribe their DCO (Developers Certificate Of Origin) I remember a lot of kernel developers signing additional declarations to clear up some licensing issue, I remember it was not all of them and can't find the reference. Basically any cleanup on the licensing side, so that you know that rust also means "the correct way"? Sure, it will take decades, but at least you would not be stuck with current "gplv2-only-dco-maybe-additional-guarantees" Can someone @Greg or even @Linus on this?
