I don't have any problem with long hairstyles. I'm using one right now and my holy grail hairstyle is a long one.
All I'm saying is that if I were developing a video game and its community requested long hairstyles, then bitched about clipping every time I added one, I would add them very infrequently if at all.
The only way around that is to either stick to short hairstyles, make all chest pieces boring and flat, or implement a robust physics engine with full collision detection that would blow up all the toasters most people are running this game on the second they step into a populated area.
If the community can accept that clipping is unavoidable and quit whining incessantly about it you'd probably see the devs be much less apprehensive about adding long hairstyles.
