It might be important because the remedy could well be different. The emulsion responds to alkalis with swelling, which improves washing, while AFAIK paper base doesn't care all that much about pH. I would therefore assume that Carbonate based hypo clearing bathes work for film and RC paper while I don't expect them to be very beneficial for washing FB prints.

When we discuss Silver Thiosulfate complexes we need to understand that there are two possible ways how they stick to fibers: it might be the Thiosulfate which somehow binds to the fiber, but I would rather suspect the Silver ion accepting some reactive group as another ligand.
