My point is that I don't like USB-C because it tries to do everything and manufacturer must implement that "everything" properly which adds cost & frustration.

My point is that I don't like USB-C because it tries to do everything and manufacturer must implement that "everything" properly which adds cost & frustration. Compare USB-C power delivery and the 12-pin cable & connector with USB-A's 4 pins and a resistor on the data lines to communicate allowed current draw, or even a barrel jack with the standard 19V ~3A PSU and no negotiation at all. Which one is the easiest to build (hint: one is easy enough to DIY) and which one is more reliable?
