yes you can use a Q/R in track drops.
i personally like the idea of semi horizontal dropouts for freewheeled singlespeeds because you can have the wheel anywhere in the dropouts without affecting the position of the brake shoes. this is useful when changing gear ratios and particularly so if you have a flipflop hub.
