The dust cover isn't intended for any protection for say a rock as it is too thin for that type of protection.
It is in my mind strictly to protect the converter/front seal from the elements, dust,dirt sand, mud, water, etc I would think that as a rotating mass it could sling a bunch of water and related gunk up and around the converter if you would be driving in rain, or on a muddy road.
Just my thoughts.
