BackwardCompatibilityCheck VS composer-normalize

It's also not a big risk because if it does fail it will fail every time you just load the class that implements the interface so probably your while site will error. If you do cursory testing of the new version before you deploy it you can find the problem quickly before it becomes a problem. You can also do static analysis checks on your code to make sure its compatible with the libraries you use including when you upgrade them. And library maintainers can run Roave/BackwardCompatibilityCheck/ to make sure they don't accidentally introduce a new interface method without declaring a new major version.

roave/backward-compatibility-check: Tool to compare two revisions of a class API to check for BC breaks

btw when I talk about breaking BC I don't really mean not compatible with something stored in the DB using a previous version of the code. I mean not compatible with other PHP code written to work with a previous version of the code. It's the sort of issue https://github.com/Roave/BackwardCompatibilityCheck exists to detect, and for which semver says you have to increase the major version number on a library.
