do you really mean skip RA or all of autoconf?
I think what makes sense is to use the parts of ipv6 that work well, RA, but blend in what works already well and is folded already into the enterprise model... dhcpv6.
i want to explore RA(only) + DHCP, to save me from running a routing protocol or vsrp to have redundant exits for a LAN.
ok, somewhere there's a blend of things that will work for enterprises and cable/dsl/mso folk. I think that some enterprises don't mind 'random address selection' while they want to pass out info required (cause like it or not DNS is required) in a sane manner, one that's even part of their current method. RA/Autoconf won't work at all for some folks with deployed server infra, all they want is a method to get a static addr on a box and route properly. Perhaps RA gets them the 'route properly' part easily enough but I can imagine places where that is even turned off. Basically my rant here is that autoconf isn't enough, it's not even a starting point for enterprise folks who rely on DHCP for all it's bells + whistles. Taking a giant leap backwards is never going to fly for them, so wake up and smell the cafe, dhcpv6 needs to be viable, workable, operable, built-in and well tested.
