It's a pure userspace question now.  Well, almost, except of the
single bit which were kept before 2.6  for each module - if it
was loaded with -k flag (auto-unload) or not.

Better question to ask, IMHO, is why network drivers don't gets
referenced properly as all other drivers are.  Because right now
they're unused even if the network interfaces are up-n-running,
and rmmod'ing a seemingly unused module will cause that particular
interface to be removed too...
