Lynching was a poor choice of words.   In any case, my point is that if you have a real need for this functionality on your network, you should be able to articulate that in a convincing way, and there should be some reason why DHCPv6 is a better solution than RA.   It shouldn't be the case that you'd just rather use DHCPv6.

What's missing from this description is "RA doesn't work well in this situation because..."

Widespread deployment requires that people have tools that work well to manage their local network.  If the tools that we have given them thus far do not work well, it should be easy to say why.   It's not the IETF's job, nor should it be, to give them specific tools just because those are the ones they want, any more than the building code should allow you to use deck screws in a shear wall just because you happen to prefer an impact driver to a nail gun.
