As an owner of a network, service, or application one must ALWAYS be defensive and understand why you place trust in another party.
Re-examine that trust with every update you apply. Sure, it sucks. But, that is the responsibility one assumes in owning any process. It's easy to #YOLO changes; but, know _why_ and OWN it.
A good deal of this article applies regardless of using SemVer or not. And beyond just software packages.
