I'm sure we can fix a few conflicts...

You don't, that isn't how kernel auto loading works. Any user can
attempt to create any kind of socket and the core kernel code will
load the correct module to support that socket. That is the standard
way kernel autoloading works, particularly for net families.

Kernel autoloading of userspace facing kernel services is always
triggered by a user process attempting to use the service, so this
comment makes no sense to me.
