Perhaps you could elaborate on this, to make clear why wl_data_source.drop_performed is essential? I think Bill assumes that any action performed here could instead be delayed until the data source is destroyed (which could be arbitrarily long) or until the next enter event (same). I guess I will partially answer my own question: you would need to delete the drag data during a move operation, for one, which cannot be so delayed.
