This is also my problem with this legislation. There is legitimate innovation in connector design. Surely people remember micro USB cables, which weren't really that good. I certainly never would have wanted them to become a mandated standard.
While I think USB-C is quite well designed, this legislation makes it extremely hard for a superior standard to arise. The only reason USB-C has any grounds to be a mandated standard is because it already is widely used. For an alternative standard to arise, first you would need to convince multiple nation state governments and/or a multi-nation government to allow the standard to be used, even before it made it to market.
