Here's a concrete proposal to address the objection [1] to the resolution of LC76c [2].
 
Suggest replacing "When a fault is generated, the generating node MUST attempt to propagate the fault, and MUST do so in the direction and to the recipient specified by the ruleset. " in 2.2 of part 2 with "Unless security concerns limit the ability to deliver faults (e.g. preventing participitation in a denial of service attack), when a fault is generated, the generating node MUST attempt to propagate the fault, and MUST do so in the direction and to the recipient specified by the ruleset."

The text in 2.1 Fault Propagation Rules sounds like a best effort must
be made to deliver the fault. However, as a security consideration, we
need to allow our customers to turn off all faults.  It's not obvious
that this constitutes a "best effort."  Please allow a specific
exemption for security measures.
