Is there any reason why we should not reject incoming TCP/UDP/ICMP (echo request) packets with ICMP type 3 (destination unreachable) code 13?

I was suprised by a machine on the internet doing so and couldn't adapt my shields^H^H^H^H^H^H^Hfirewall rules with iptables in a similar way. Both iptables (--reject-with option) and the kernel need to be updated for this to work.
