With link-local addressing and ip verify unicast reverse you're
not going to see any TTL exceeded traceroute packets from link-local
addresses anyway. And no ICMP size exceeded packets either, which
was my point.

But indeed it should be 'ip icmp type <TYPE> source <IP|INT>',
with at least a default 'ip icmp type 4 source lo0' or similar for
interfaces with link-local addressing.
