USB-C electrically is nearly identical to USB Type-A, assuming you're talking about a USB2.0 implementation. You get the same problems on USB-C as USB3.0/USB3.

USB-C electrically is nearly identical to USB Type-A, assuming you're talking about a USB2.0 implementation. You get the same problems on USB-C as USB3.0/USB3.1 Type-A, assuming you're talking the same speeds. Also, despite there being relatively tight tolerances, USB controls tends to be really tolerant of not meeting specs... if only because not everyone does meet spec. I doubt that 4-pin connector causes any meaningful issues, even at USB2.0 high speed.
