IMO, a stalemate should count as a loss for the player inadvertedly causing it. Even as a draw, it is a bad outcome for the player with Raumvorteil. White can always retreat some pawn to allow controlled movement of Black, occupy the starting square where black came from, pulling out the black piece and capture it with the King. Finally, White has a way to win in this situation.
