I guess there's some good to it. For example, the sheltie's standard. If they were to change the height standard, some people wouldn't be able to tell the difference between a collie and a sheltie. But some, I'm not a fan of. For example, the border collie's standard. I'm not sure if they updated it or not but for a while, some of the "best" border collies only looked good and wouldn't be able to herd at all.
