I agree. The issues have been tagged along multiple axes: importance,
complexity, backwards-compatibility. So is it just a question of agreeing what
the minimum bar is? Yes I should take a look at your doc again :-)

Hi,
Yes, I support working on YANG v2, and this document and the underlying github
repository to back it are a good approach.
I do have concerns that the scope and goal of YANG v2 is not well defined - I
think that we, as a community, need to understand and agree what the goal is of
the next version of YANG and which of the 150+ proposed enhancements tracked by
github we plan to fix and included in YANG v2. I don't think that an approach
that just relies on individual contributors working on the issues they have
most interest in is the best or right approach.
To that end, I published a doc during the last IETF meeting
(https://www.ietf.org/archive/id/draft-wilton-netmod-yang-next-agreement-00.html),
with a goal of trying to further the discussion about both what specific
issues tracked on the github issue tracker could/should go into the next
version of YANG and also which changes should not end up in the next revision
of YANG, and which changes we probably don't want in any version of YANG
currently being considered.
A comparison could be drawn to XPath. XPath v1, whilst it has some flaws, is
still a small language. The subsequent versions of XPath are all significantly
larger languages, with presumably a much greater implementation cost. Care is
required, I think, that YANG v2 doesn't immediately follow this same path.
Kind regards,Rob
