I think there are still some potential obstacles like diagnostic devices (how to diagnose phone that doesn't boot without a cable?) and pricing - adding magsafe by default would probably raise costs
What do you mean by this? All iPhone models currently sold by Apple (except for the SE model) have magsafe and wireless charging by default.
They could also just have a non-charging Lightning port on the phones and say screw you to the EU :P
Small, non-charging port? (Not Lightning. Smaller.) Or just a sealed device that needs non-contact diagnostics. If the EU pushes back, they can make one that’s used serviceable but floods. Maybe that’s a valid marker niche.
