USB-c has a bunch of futureproofing in it, like a bunch of pins that aren't used yet. And even without those pins, is supports usb4v2, which has 4 lanes of PCIe 4, and they keep doubling the speed every minor release of usb.
If we get to a point where those other pins are needed in the next decade, I'll be surprised.
So unless there is something physically problematic with the connector, like after all this time we suddenly realize that the design causes failure in some common scenario, or material science leaps ahead and the port becomes too large for consumer devices, then it's probably good that they're not making a new standard.
