It also opens up more lanes for adding more USB ports or faster usb ports. Such as usb 3.1 gen 2. Or it frees up more lanes for more NVME devices.
And thinking about it it is quite sad that PCIE needed over a decade to achieve what Ethernet got over 4 physical contacts and a much longer distance. Not the same, I know, but just the difference in distance should make up for that.
