Again, who cares if the OK makes the distinction or not? If giving a hechsher to chalav stam makes them problematic, why would that distinction change anything?
The way I understand it, the OK tries to portray itself differently when it comes to restaurants than when it comes to wholesale food manufacturing.
Many have said that having OK supervised eateries in Crown Heights was already a step down, but that barrier has already been broken for a while.
Is there something in the drinking water of that corner, that makes all the Kashrus supervision there go to another level? Calabria taking a Hechsher from Monsey, Basil going certified by owner, and now by OU.
