Yeah and the biggest problem with that hard transition was that even as a well-behaved Mac user going all-in on USB-C, you'd quickly run out of ports, and there were literally no USB-C hubs on the market for years. Now they exist but cost a lot more than -A ones and have caveats due to varying capabilities. So -A peripherals still make sense even with -C laptops, and most things I see are still -A.
