I use the definition for theory as a hypothesis that has received sufficient experimental validation. So, by definition, many of the frontier quantum-gravity stuff doesn't fit this, unfortunately as compelling and fascinating as they are.
Again, I'm just agreeing with what s/he said, that unless we have experiment/observation, we don't know whether this really describes our universe's origins and/or evolution.
