Using Cheesecloth for Pancetta

I am making pancetta for the first time and I've just taken it out of the cure to dry. I have rolled it and am ready to hang it. Before I hang it, what are the pros and cons of wrapping it in cheesecloth while it dries? The recipe I am using says to cover it in cheesecloth when laying flat to dry, but nothing about wrapping it in cheesecloth to hang it.
