SemVer is generally good practice but I don’t like promotion to religion. For example, during the pre-release of the firebase-functions SDK we shifted SemVer by one: 0.2.1 was a feature addition from 0.2.0 and a breaking change from 0.1. Similarly there are rare cases where I’ve swept breaking changes under the rug because they were severe bug or security fixes that affected a corner case unlikely to be seen in the wild.
