They weren't specifically required to drop AWDL, they were just required to implement WiFi-Aware in such a manner that neither technology had an advantage.

In theory Apple could've maintained both, but that seems like a waste of development time to me.

I doubt they would've had to implement any specific protocol if they had just opened up AWDL, but I suppose they'd rather keep that closed to maintain the ability to guard their walled garden in non-EU devices.
