How should a generic tool know what kind of actions are needed for given
function to be removed?  If you ask me, there should be a way to unbind
gadget and unload all modules without any specific knowledge of the
functions.  If there is no such mechanism, then it's a bad user
interface.

I think the question is of information flow direction.  If user gives
some information to the kernel, she should be the one creating any
necessary directories.  But if the information comes from kernel to the
user, the kernel should create the structure.
