BUT WHAT THE HELL IS THE POINT?

Don't you get that? If the sysadmin can turn the filtering off, so can any
root program. And your worry seems to be the CRM kind of disk locking
utility which most _definitely_ would do exactly that if it is as evil as
you think it is.

And if you hardcode the filtering at compile-time in the kernel, that
means that you've now painted yourself into the corner that you already
seemed to admit was not a good idea - the same way it's not a good idea
for network filtering.
