The country where I was born changed the definition of car when I was 20, the country where I live now changed the definition of aubergine quite recently. These things happen. They're bad if your viewpoint is that the old definitions are holy scripture. If your viewpoint is that the definitions serve goals, and we learn more and change the way we approach those goals, then the changes are generally good.
