The kinky layer-2 stuff I've seen some places do tells me they won't be able to deploy IPv6 without it.  

I think the key here is "feature parity" and the whole "96 more bits no magic" aspect.  The option is low hanging fruit to solve a problem.  Perhaps it's just a conceptual problem (eg: DHCPv4 gives me option #4.  I should have a comparable option# in IPv6!).

While I may not need option #37 (or folks may not use it), sending a RS in addition to DHCPv6 request is two steps in host configuration, whereas one should be able to suffice (perhaps).

It's also about authorization though, I could get a RA back from the RS from an unexpected (rogue) device in the same way I could see a rogue DHCP response as well.  I have logging on my DHCP server, but I don't have that capability from a RA/RS stance.  One is central (but perhaps relayed), the other is local (and never relayed).

Seems a lot of emails over something simple that's not much creep and just "parity".

(enjoy other great options here: http://www.iana.org/assignments/bootp-dhcp-parameters/bootp-dhcp-parameters.xhtml#options .. I need my quotes server for IPv6 via DHCPv6 too).
