No. sfstns.tbl covers most of NCEP's needs, but I generally find additional and add those in to sfmetar_sa.tbl which is what the pqact action I provide is using with dcmetr. Since I amusing data from several sources, and there may be errors in any source, I make modifications to sfmetar_sa.tbl and not the distributed sfstns.tbl. Clearly, historical location and information is a problem. NCDC is working on that problem, but many of the smaller FAA locations are not in their database. The 5.10.1 release has quite a few updated Canadian and Mexican locations as compared to 5.9.4. Greg Thompson has a station table he maintains as well- and the MADIS data sets should have locations within the NetCDF files if you are able to cover your area from that source.
