What kind of other Haki coating is there beside what have already seen? CoA and CoC come from the same power system, Haki, so their application of Coating and Flow must have similar aspects.
If you were to say that their affects are not similar I could go with you. CoC, unlike CoA, in general affects the Will/Haki of the opponent so for its Coating/Flow applications to also mainly affects the Will/Haki of the opponent but in a more concentrated way is very plausible.

Remember when Zoro first used CoA in Alabasta he could hear the breath of all things.. So space itself air molecule and stuff have will power may it be very low and with CoC you can overwhelm or pressure a given space near you creating CoC flow barrier..
