I'd say it highlights one important aspect of IPv6 deployment, namely HOW
you deploy it. Marc's test shows perhaps that dual stack may introduce
unacceptable risk to existing infrastructure.

Carriers might not want to dual stack their existing mobile broadband
gateways, because the Internet access architecture for mobile is often
achieved through a choke point (one firewall cluster filtering the traffic
for all the mobile clients), quite unlike regular "fixed line" Internet
access, where each customer has their own RG/CPE.

Enabling IPv6 on that cluster could potentially ruin the day for the
millions of existing IPv4-only mobile customers; it may make business sense
to process IPv6 in a separate cluster (in this example).
