Backwards compatibility, why?

This is quite an interesting topic. I am currently attending a session on EJB 3.0 and JPA given by Patrick Linskey which has been participating in the spec work. An issue related to backwards compatibility related to some things introduced in JPA (global named queries). And I asked if Patrick sees it as much of a problem to break backwards compatibility. And he said, "we did it with EJB 3.0 and we do not want to do it again". Well I have never ever heard of anyone actually complain about this compatibility break. In my opinion in many cases the effort spent not to break backwards compatibility is just a waste. We would be much better of getting new specs and implementations that improves faster as opposed to versions that does not break backwards compatibility.
