The regulation does not require devices to only support USB-C, just that they at least support USB-C for charging. They can always have multiple ports. If the 40Gbps offered by USB-C is really not enough for you, then your device is probably big enough that multiple ports does not mess up your device's form factor. Also, the regulation does not require devices to support USB-C forever, just that all devices support the same open charging standard. That standard can and will evolve over time; maybe not as fast as it would if not regulated, but it's pretty contrived to think it would actually stifle innovation.
