In practical terms that doesn't really happen. People still use device specific cables. If I have 4 USB-C devices and one lightning device I have 5 cables. If I replace the lightning device with a USB-C device, I still have 5 cables. The only time "cable consolidation" matters is when traveling or in a backpack.
My USB-C security cameras need their dedicated cables, my Oculus Quest needs a dedicated 16 ft cable, my random amazon junk device cables don't support the PD that my laptop requires, etc. By forcing everyone to use the same tips without enforcing featuresets all its doing is confusing consumers even more. To all my older relatives and non-tech savvy friends, an iPhone cable is an iPhone cable. It's way less confusing than figuring out the right power brick wattage and cable combination and wondering why this USB-C cable doesn't transmit video to that monitor.
