That would be great in theory, but who would actually review and enforce that? Without really strict rules in place this would be doomed to fail. You would need to have a huge number of people whose job it would be to review every single software/firmware submission. Would you mandate that companies must deliver code and build scripts that can be built with a single command and produce usable software/firmware? Otherwise companies would probably submit random archives of plausible looking code that will never be usable because it depends on 100+ proprietary components.
