There have been some that as you note could be tested. The big ones though can’t although they do have problems - as often their proponents fully admit. Lee Smolin for instance is pretty forthright about the limits of Loop Quantum Gravity. Of course Smolin is quite the Peircean so I’m biased towards him. <grin>
