And my experience as a routing operator/geek says that traceroute must
work. "unnumbered" links are a pain to no end in day-to-day ops.

When I was last working for a large ISP we had one in-country sub-ISP in
Sweden who used unnumbered p2p links to customer CPEs. No end of pain
with monitoring and troubleshooting.
