I think if we asked telstra why they didn't filter their customer some
answer like:
 1) we did, we goofed, oops!
 2) we don't it's too hard
 3) filters? what?

I suspect in the case of 1 it's a software problem that needs more
I suspect in the case of 2 it's a problem that could be shown to be
simpler with some resource-certification in place
I suspect 3 is not likely... (or I hope so).

So, even without defining what a leak is, providing a tool to better
create/verify filtering would be a boon.
