I had thought fernando/jen's set of documents pushed forth a basic set
of protections (or possible protections) for IPv6 hosts, things like:
  filtering the right set of icmp type/code
  filtering of fragments in the wide area
  inability to use certain header types (due to similar filtering problems)

a quick look through their author profiles:
  https://datatracker.ietf.org/person/Fernando%20Gont
  https://datatracker.ietf.org/person/furry13@gmail.com

shows a raft of documents related to host/network problems with ipv6.
I suppose: "Yes there is no overarching architecture, design,
implementation, threat-analysis, requirements document set for this"
(nor something that walks readers through the published documents and
shows where gaps may be (or what gaps these documents patch)

sure!
