Sorry @taeric, I can't reply to your post directly.
I do think that the intent of the producer is being communicated (unsafe to upgrade, safe to upgrade with new features, safe + automatic improvements).
I'm not disagreeing that "spec" adding more metadata to have better granularity and potentially reducing the amount of manual work is a good thing. But in the absence of it, "semantic versioning" is an improvement over safe and unsafe versions being indistinguishable.
