Except for Yum, which has for years been the only method that was both 
secure and practical anyway, but I agree. As long as people are being 
discouraged from upgrading by Yum because it's "unsupported", removing 
the only "supported" and secure upgrade method is definitely a 
regression, and quite irresponsible.
