In this case is a money "problem" and also if a player is really bothered by this kind of thing most likely is already using a short hairstyle, like me. The option to adapt every hairstyle is why we don't get that many, it does not only make it for each race/sex but you also had to adapt it for every headgear variation.
But yeah, SE care about this stuff, you can tell, but here perhaps the ultimate problem is players choice, certain gear doesn't mix with long hair.
