I am not much familiar with Ansible/Puppet etc. However working in Java and dealing with frameworks like Spring/boot, kafka etc I notice a phenomenon of large number of breaking changes, specially when one update in couple of years as opposed to update with every release. Now when I dig into changes it just points to extremely poor design to begin with. It just couldn't handle slight change in requirement without breaking changes.

I do not think it is a case of hindsight 20/20. These are basic things like object need multiple fields but it is rigidly defined with 2 fixed strings and now one need object V2 to update. Or all functionality dumped at base URL so no scope of adding sub-functionality without breaking the whole pattern. I can understand no one can plan for how complex functionality evolve over time. But here I see perennial amateur hour with every release. And it is doubly irritating when these frameworks are already many layer deep stack of bullshit abstractions so ideally they should be able to handle changes without breaking.
