This has similarities with my wish to detect when ICMP unreachables is 
sent from intermediate routers and not the target. It has been discussed 
a couple of times. Some reasons it isn't implemented:
a) My programming skills is just enough to make a PoC and I haven't 
convinced anybody else to do it :)
b) We aren't sure how to put the info in the output. The human readable 
that is. XML output is no problem.
