Part of this proposal is removing optical media from supported installation methods. 

From your point of view, Fedora is broken right now because, for example, it doesn't work from USB Media created by UNetbootin most of the time. It'll be the same, optical media will get delisted from supported installation methods, so Fedora wouldn't be broken if it doesn't work from installation source created using an unsupported method/media . .... Or, if you don't agree with that, then it's already broken ;)
