As I remember it was decided that it could be dangerous to allow
module unloading.  The main problem was that of potential for race
conditions.  For example a programme might be using a device when
another one unloaded it.  Usage counts were meant to prevent this, but
were considered unreliable.  As a result the ability to unload modules
is now a configurable option in the kernel, along with forced unloading.
