I completely agree that, when interoperating, you have to follow the
rules, and I would (naively) hope that "customers cannot reach me
because of my configuration choice" is sufficient incentive to fix the
problem for the majority of network operators. But what I am arguing
against was the stance some people take against DHCPv6, or prefix
lengths longer than /64, or other internal-to-my-network,
why-should-you-care choices I might make. Telling me it is dumb is
fine; implementing software/hardware/protocols such that I can't do it
simply because you think it is dumb is a problem.
