I’m not sure what you lose by the expansion bay port being an actual standard port rather than something proprietary I’m assuming is what you would prefer? There is a grip system where the expansion ports lock in, and the ports aren’t just hanging by the USB-c male, I have not heard of instances where the inner port fails. In fact, it’s pretty convenient and has come in handy for me that in a pinch you can remove the expansion modules and have extra usb-c ports.
