Absolutely.  I think the issue really is just whether or not the IETF DTN WG will be responsible for maintenance and extension of BPv6 in the future.  And maybe that's simply not an issue.

Coming into this late, no one has mentioned the analogy of IPv4 and IPv6. IPv6 did not obsolete IPv4 when it was published over 20 years ago. Had IPv6 come out and said "obsoletes IPv4" at the time of its publication would we now have an all-IPv6 Internet today? Probably not - operational experience with IPv4 would have continued along its then-current trajectory extending up to the present day.

It is the same with BPv6 and BPv7 - there is a non-negligible deployment of BPv6 that will still continue after BPv7 is published whether we say "obsoletes" or not.
There is operational experience with BPv6 that will continue onwards the same as happened with IPv4, and that is not a bad thing.

Fred
