"charging while using" is a pretty core use case. Are you expecting people to buy a bunch of cords with big dongles on the end? At that point the EU probably would still have grounds to take action since "magnetic attachment point port" isn't exactly "no port."
If you're tethered to a cord that's attached to your phone in a specific spot can you be said to not have a "port" even without part of the cable going "into" the case?
I suppose the lawyers would get paid a bunch to figure out how flexible the definition of "port" in the regulation would be. "Port" in networking is obviously purely a concept vs a physical hole. "Port" in shipping is also more conceptual, no two ports need share the same layout.
