@PattaFeuFeu @luana @bcoffy in the USB-C spec it says they're not allowed because "such adapters would allow many invalid and potentially unsafe cable connections to be constructed by users" (e.g. stick two of them onto a USB-C to C cable and you get a USB-A to A cable). they're pretty safe so long as you know what you're doing with them, they just don't want people sticking the wrong things together and breaking their electronics
