If you read the introduction RFC 3633, it is easy to see why people have that impression.  Even the example you site is related to Internet Connection Sharing (ICS) where Windows is basically acting like a CPE router. I'm not sure what to do about it though, but it probably shouldn't be ignored.

Yes, that helps a lot.

A suggestion, use it if you like, I think what you have is sufficient, I just think this would be even better:

   While [RFC3633] refers to the DHCPv6 client is a "requesting router", ....

Also, we should make sure similar clarifying language gets into rfc3315bis which as far as I can tell will incorporate and obsolete RFC3633.

Thanks.
