cups userspace -- trusted programs?

Hey all, I'm wondering if the intent of the cups userspace tools are to be trusted programs? Specifically I'm curious about cupsaccept, cupsreject, cupsenable and cupsdisable. The reason I ask is because if they are supposed to be trusted programs, they don't generate unique audit messages like other programs. Personally, I think these tools should generate messages since they are a source for leaking information, and therefore should be restricted to administrators. Thanks, Mike
