Semver and this are orthogonal. Semantic versioning is about the semantics of an interface (rest or otherwise). This is about the version of the underlying implementation. “LTS” of a semver api is driven by backwards compatibility, so it’s the second section (1.2 vs 1.3). Declare the “not before” and “not after” of the semver and you have effectively defined lifetime.
