How people implement RFC 3225 does differ from the intent of the author, however I would be surprised if this is what DO is taken to mean in any resolver.

You're suggesting RFC 3225 should have predicted DNSSECbis?  Would it help if the interpretation of DO is that indicates the resolver supports "DNSSEC as defined at the time"?

This probably isn't the right venue for this discussion.
