[1] - If the issue is the use of the term 'insert', which is too close to the 'SRH insertion issue', I'm personally fine with using a different term. E.g. "add". Please propose any term which suits you [1]. That been said, I hope that we are not in a situation where words are being forbidden. [1] Preferably in the related thread, in order to help everyone (all WG members, chairs, shepherds, ADs, IESG) to be able to track all comments. As we'll likely be in a situations where the number of emails may be consequent > Why would draft-voyer-6man-extension-header-insertion exists if the SRH > proponents do not intend to perform SRH insertion? As of today, the question been asked is a WG last call on draft-ietf-spring-srv6-network-programming. If you want to secure that SRH insertion is not used in the document, please comment as part of its last call. That been said, thanks to your comment, I've seen an unused reference for [I-D.filsfils-spring-srv6-net-pgm-insertion] that needs to be removed --Bruno > > Brian > > > > >> A question of you as a chair: does the wg you chair publish documents > >> based on current specs (or at the very least based on changes that are > >> going to happen in the near term as a result of *existing and proven > >> consensus*), or does spring ship documents that implicitly betting on > >> changes that have no consensus? > > > > In general, I don't see the benefit of sending a draft which we expect > > would never progress to RFC.
