> But it's certainly another step along the way to DNSbis by accident. Would it be useful to make it not "by accident"? That's why I have a love-hate relationship with TLV inside DNS messages. I have a couple questions: a) make DNS over TCP/TLS sessions without TLV suck less? b) make this draft DNS-SD only, so it can fast forward... c) use the changed paradigm to work on DNSbis without the accident part?
