You're changing the subject slightly. :) The thread is about letting a legitimate user continue to safely use the system; you're talking about limiting the damage an attacker can do. The two are related but different. The idea might be good for damage mitigation; but for permitting continued normal operation, it's IMO a non-starter on every level.
