Relax, while mentioning the real world without any criticism for the soundness of the solution is absolute nonsense, some would say idiotic, thinking only in the absolute best solution given your narrow world view is not any better.

While I agree that my view is narrow, the "best solution" in question is what we used to do, and it was fine. There are still many places that manually manage dependencies. Fundamentally automatic software versioning is an under-developed area in need of attention, and technologies like semantic versioning which are ubiquitous are closer to suggestions, and not true indicators of breaking changes. My personal view is that fully automatic dependency version management is an ongoing experiment and should be treated as such.
