All examples of this paradigm fail due to two factors:<\/p>\n<ul>\n<li>The lack of any experimental evidence for these new degrees of freedom.<\/li>\n<li>Whatever you get from new symmetries carried by the extra degrees of freedom is lost by the fact that you have to introduce new ad hoc structure to explain why you don&#8217;t see them.<\/li>\n<\/ul>\n<p>There&#8217;s also a bit about the new ideas I&#8217;ve been working on, but that&#8217;s a separate topic.
