Right now there is many a network you cant traceroute through at all due
to their use of local scope addressing.
For those networks a feature such as this one would be a nice improvement.
Conceivably, the network could be able to view traceroutes across their
own network unmasked.
The truth of that matter, that while hardly convenient and scalable in
any but the smallest of implementations, control plane or border nat
translation achieves the exact same results as the proposed feature.
I dont believe the results of a proper implementation of this feature
must be as drastic as you paint them.
