But then someone supplying such an arg may need to update their
userspace multipath config file before they can use this new kernel.

Past experience suggests that changes like that usually come back
and bite us.  Let's instead just have the kernel log a message noting
that the args have been ignored and allow people to deal with it at
their leisure.
