The Viktor's comment came before the end of WGLC, so the WG needs to consider his comments, and needs to reach consensus. Considering the fact that cosensus has not yet _obviously_ been reached (there have been positive and negative responses), the WG's chairs may need to make a call for consensus (or maybe the chairs think consensus is obvious?). Consider this my encouragement to the chairs that they make a call for consensus. > ticket request document, as it was adopted, was specifically a > mechanism to request multiple tickets so as to *avoid* ticket reuse. TLS 1.3 already does that. The adoption call is nowhere near as specific -- in fact, it says nothing about purpose of the extension. The TLS WG charter doesn't mention it. The abstract of this I-D says, among other things: This extension aims to provide a means for servers to determine the number of tickets to generate in order to reduce ticket waste, while ^^^^^^^^^^^^^^^^^ simultaneously priming clients for future connection attempts. That number could be zero, and indeed, that's allowed. "Zero unless you won't allow me to reuse this one" seems clearly in-scope to me. That you have no need for it, doesn't make it out of scope or a bad idea. Moreover, I posted an explanation of why this extension will cause Postfix trouble. That deserves a substantive response (and IETF process may even demand it). Nico --
