It may be a Saleability issue, in which case it would not be saleable without some type of floor covering. If I were doing the appraisal I would call for some type of floor covering to be installed. If the DEU wants to accept it without it, then so be it. It puts the house in the category of being unfinished. FHA does not make loans on unfinished houses or rooms in houses.
BTW, with the new housing bill, only Certified Residential Real Estate Appraisers will be able to do appraisals for FHA. See text of housing bill waiting for the Presidents signature:
