SemVer stops being enough the moment bots and coding agents can push dependency bumps across dozens of repositories. Rust's decision to bake cargo-semver-checks into std's CI and Python's gap around reproducible builds both point to the same operational lesson: downstream compatibility testing and build reproducibility must be platform features, not optional polish. Expect automation to fan out failure fast; the practical move is to provide gated, reproducible verification and make independent verifiers part of your index or CI story.
