Try using a Macbook8,1 sometime (or iPad Pro for that matter). There isn’t size or weight budget for swappable anything. Connectors take space, mechanical retaining pads and clips do too.

This is like wanting a headphone jack or usb-A or SD card slot on an iPhone SE. It’s a step backwards, given the size and weight. We’re actually at the point where the thickness of a micro-sd card slot cage matters.

Any weight budget that could be used for such things almost nobody ever uses is rightfully used instead for battery.
