Considering the *working* heritage of the GSD breed, there are very valid reasons for considering some coat types faulty.
The standard stock coat is the most maintenance free and weather resistent. This is why it is the preferred coat type and the only type allowed under the standard.
A very short stock coat, with little to no undercoat, called a "close coat" or "mole coat" is faulty because the lack of undercoat provides less insulation against heat and cold and less water resistance. Things that are important to a dog working outside in all sorts of weather.
The true long coat (without an undercoat) has the same problem. Lack of water resistence and insulation. Plus, the long outer coat is more prone to matting, picking up burrs, etc... if the dog is out running around in fields or woods all day.
The long stock coat (long coat with an undercoat) used to be accepted under the standard, and in 2009 it will be accepted again, though was still never considered desireable, only permissable. The presence of undercoat ensures proper insulation and water reistence, but that longer outer coat still means more chance of matting, burrs, etc... compared to a standard stock coat. So while a dog with a long stock coat working outside in all sorts of weather wouldn't be as handicapped as a mole coat or long coat, it is still not as low maintenance as a standard stock coat.
The bias against coats is not some elitest nitpicky attitude. It is respect for the breed standard. And the coat requirements of the breed standard are not there for some arbitrary reason or because someone just didn't like them. They are there for a very GOOD reason when we consider the origin, heritage and purpose of this breed. The fact that 99% of GSDs are now pets and no longer all weather working dogs is not a valid reason to throw out the standard because the standard is what defines the breed and makes a GSD a GSD.
