IMO it is safe to go one step further and just also assume that both updated resolvers also support DoT, and the concerned stub resolver should then use it to connect to a resolver if the latter is nowhere to be found in RFC 6890. Otherwise you would probably have to assume that all the middleboxes are also updated to support sudden JSON in the RESINFO responses without simply dropping it as e.g. likely malware-ish, or just suspicious. And then those middleboxes would also probably want to take part in the game which would also mess things up. -- Töma >
