I'd be fine with a pop out style port for those ports. Won't be flush while in use, but I'd happily accept that to trade off having to carry around dongles. I'd rather pack and carry a small "stick" of these modules stacked together than a bundle of dongles.

I give it three months tops before someone starts selling a Pez-like "dispenser" that stores these modules. If the module bodies were designed to stick together though, that would spark joy in my inner Marie Kondo.
