What I hope that means is, I can get amber turn signals (hacked/unlocked) because German brands think Americans like combination brake/turn signal lights which I think is something nobody ever thinks about. How many Honda and Toyotas have they sold with amber turn signals. Do we care? no. Instead this is due to our abritrary requirements where a turn signal must be a certain size instead of just a brightness level the EU has hence why they're so thin. That said, think the sizing does have some merit as with Tesla Model 3's, they just cut down how much brake light you have to fit the amber turn signal making both super small.
