Well just because you don't utilize all the features of USB-C, that doesn't make them unnecessary.

For example: my PC refuses to POST after replacing the CMOS battery and I cannot for the life of me figure out why. So in the meantime I've been using a USB-C dock for my phone which breaks out the port into full-sized DisplayPorts and USB-A ports, that way I can use my phone as a desktop PC until I can figure out what the hell is wrong with my actual PC. I'm extremely grateful that USB-C has all these standards built-in, otherwise I'd be completely without a computer. The built-in desktop experience on Android works well enough for most tasks.
