But why are you making it so that this can not be a module anymore?  You
are now forcing ALL Linux distro users to always have this code in their
system, despite not ever using the feature.  That feels like a waste to
me.

What is preventing this from staying as a module?  Why must you always
have this code loaded at all times for everyone?

thanks,
