Speaking as WG Member: 

Here is the update I intend to submit today:

   Additionally, in Section 2.4.,first paragraph, "Changes to the Hello
   Packet Processing", the text is updated to remove the non-inclusive
   terms pertaining to unreachability handling as follows:

      When an OSPFv3 router does not support this specification and an
      interface is configured with the Instance ID corresponding to a
      IPv4 AF, packets could be routed toward this interface and
      dropped. This could happen due to misconfiguration or a router
      software downgrade. Packet reception and dropping on an
      interface not configured with the packet AF, e.g., IPv4 is
      possible because a router that doesn't support this specification
      can still be included in the  SPF calculated path as long as it
      establishes adjacencies using the Instance ID corresponding to
      the IPv4 AF. Note that OSPPFv3 Router-LSAs and Network-LSAs are
      AF-agnostic.

         Figure 1: RFC 5838, Section 2.4 - Updated First Paragraph

Thanks,
Acee

    No reason beyond the fact that we didn't comb through the documents enough 
-- the initial focus being put on terms that may show up on CLIs.

    If there's no objection we can update the draft.

    Also, if there are other terms that we missed, please point them out.

    Thanks!

    Alvaro.
