I agree. SemVer doesn't give you permission to make breaking changes -- it documents your decisions, assuming you're honest with SemVer.

This is very very useful. You can look at a library or dependency and weigh out if frequent, breaking changes are ok for you or not -- is the value worth the pain? Alternatively, if the major version never changes, you can have more confidence that you won't have to rework your code on every library update.
