Indeed. USB-C is already a lot more feature-rich now than it was when initially designed, yet it hasn't necessitated moving to a different port or broken protocol compatibility with older USB versions.
I'm just pointing out that even if we decide to move beyond USB-C, the law already allows for that.
I truly don't understand why some are against the law pushing for a standard here. Would these people like it if different branded lightbulbs used different sockets? Or their TV, toaster, washing machine, playstation etc all used different plug sockets? Or only Volkswagen garages had fuel nozzles that fit into Volkswagen cars? Standards are a good thing.
