It hasn't yet become a problem, so we haven't worried about it too much. I worry a bit that some policy we made up to deal with problems that don't exist yet might do more harm than good. If it ever becomes a problem, we can formulate a policy that deals with that issue specifically.

I suspect that I may come to regret those words someday, but so far it's worked pretty well, so I'm stickin' with it. ;-)
