 Speaking as an individual, but drawing on my experience as a contributor
 to one of the profile specifications you mention, it seems this draft
 could be one of the following:

 1.  a roadmap/reading list for IPv6 implementors and evaluators (thus
 informational, and without any RFC 2119 language)

Would this type of document be a single laundry list of IPv6-related specs or would it try and narrow down the suggested reading list based on some classification (e.g., router, host, etc.)?

While TCP roadmap (RFC4614) title is worded as a "roadmap", it's in some respects closer to an applicability statement. That is, rather than just listing the specs, it classifies them to "Basic Functionality", "Recommended Enhancements", "Experimental Extensions", "Historic Extensions", "Support Documents", "Undocumented TCP Features". In a summary of each RFC, there are also statements which reflect outdated parts of the spec.

I grant it that IPv6 and TCP are a bit different. TCP has a clearer "minimum implementation requirement" which is the same for all kinds of deployments. It's not obvious what that would be for an IPv6 implementation.

I don't think the IETF is best placed to develop different IPv6 implementation profiles for different usage scenarios. It seems to be the job of the market, ipv6 forum and organizaitons like that to do that. We could help in that process, and I'd hope we'd get feedback on the viability of our specs in that regard, but trying to write RFCs would likely be difficult.

So I think we would be best served by a TCP-roadmap like document, which we could call either a roadmap or applicability statement. It should not have any RFC2119 keywords.
