Please note that we're still discussing this change. We work out in the open so you can see us working on it.

Discriminating on origin is likely illegal.
It sounds like you just need to harden your production perimeter. Jump boxes with two-man-rule access and terminal logging. Apply the same practices to data as you do code.
