I agree, as a LSM module, this purpose is a no sense, because it will
avoid using another security module.
On the other hand, adding this capacity directly to the syscalls seems
to be a little bit ugly (it reminds me security post_accept hook
strategy of returning or not a value). 

But the way to go is to add this directly to existing security models,
if it make sens for them.
