I think that is largely changing. Quite a lot of breaking changes to clean up ancient cruft are slated for 8.0. For example, PHP has infamously had broken ternaries (they're left associative, which is never what you want, not how any other language works, and a rich source of bugs). Nested ternaries are being deprecated and will be removed completely in 8.0; in a future version correct (right associative) behaviour will be able to be added. Obviously there's a long road to go, but being willing to change how an operator works on that level demonstrates a willingness to break compatibility when necessary.
