I can generally agree with this save for two cases. One, I've found that major bumps in a programming language are significant, especially in the case of something like python 2 vs 3. Second, a lot of major javascript players have been using major bumps mainly in the case of breaking APIs, removing functionality, etc (ex: Lodash, ExpressJS, and - soon - React). Contrarily, I've noticed in Rails that A LOT of major refactoring and functionality has been added via minor bumps that, while still backwards compatible for Rails itself, often breaks custom implementations, usually related to javascript modules and configs. Overall, though, I agree with you.
