This to me is one of the least credible claims of the RA/SLAAC crowd.
On the one hand we have carriers around the world with millions and
millions of customers getting default routes and other config through
DHCPv4 every day. And most of the time it actually works very well!

On the other hand we have RA/SLAAC with a vastly smaller customer
base, vastly less real life testing - but which is still claimed to
be so much better that DHCPv6 is not *allowed* to get a default route

The mind boggles.
