WG-objections of the form "my pet-issue isn't picked-up" should not be used to fail adoption (or, later, the WGLC).  Of course, objections to how the specific-issues picked-up were resolved are valid.  The goal being to most expediently (<1yr) forward the versioning work in a correct (contract-compliant) manner.  Support?

I hope that (i) doesn't happen.  I think it is the proposed changes in
draft-ietf-netmod-yang-module-versioning that require a new YANG
version.  If this new YANG version allows for other versioning schemes
than revision-date, then we can keep the modified semver scheme
outside the core document.  (I don't like the name "YANG semver",
since it sort of implies that this is something that is required by
YANG the language.)
