The "cemented" tradition you mention may be in part because of film and video became available but were expensive to start with. Now it may be the opposite, because one can now see all over the internet how forms tend to mututate. Overall its made the study of forms a lot more interesting. Now all this makes it easier to understand a form's structure and applications, and also compare to written and musical sources connected to them.
