Well for a data-point, similar order went into effect yesterday in Michigan and it didn't impact anything in the Skyclubs in DTW.
Single-serve food options were the same, and the bartender serving drinks in the bar area.
What I did notice in the terminal was that all restaurants had closed-off their tables/seating area and instead you could still order "take-out" but just had to eat it in the gate area seating.
....it is what it is.
