Perhaps encode feature flags into the last digits of the SOA's Expire time? For example kumari.net <http://kumari.net/> has an expire time of 1209600, and those last two (decimal) digits could be used for binary encoding feature flags, so 1209601 = DoT, 1209602 = DoH, 1209603 = DoT and DoH, and so on. This gives us 6 feature flags we could shove into Expire time. -d
