I also think that there is significant value to splitting the NETCONF and XML specification out of RFC 7950 (but keeping XML examples). I think that this may be beneficial to YANG’s longevity, and I’m sure that it would make it easier to maintain and extend the NETCONF/RESTCONF/YANG document set in future.

This doesn't necessarily mean closing the NETMOD WG, it would IMO be immensely useful to rewrite the language specification and remove NETCONF- and XML-specific part. +1. There are plenty of ambiguities and NETCONF/XML pollution in the spec. Having the specifications in a DAG would be immensely useful :) Agreed and I should've mentioned before that Martin said in Prague that he'd already started this effort, seeing it as a necessary pre-step before making other changes. I'm unsure if the intention is to release this by itself as an RFC 7950 bis but, if looking for a minimal change, that might be it. The next rung up would be to just add clarifications. The next rung up from there would be to add only backwards-compatible changes (currently targeted by [1]). The last rung being to also target NBC changes (there's no consensus to do this). This WG sure likes to spend time refactoring documents. Moving lots of text will create bugs and strong coupling, and only help the standards purists. It will be a lot of work for the WG and IESG to review such a massive document split, and in the end we have no improvement in YANG, just more RFCs to read.
