Yes, but this is a generic rubric to apply to all frontiers of science: falsifiable theories are good; unfalsifiable theories are bad; even when you falsify a theory, there will always be room to fudge and rescue it by making it more baroque; the principle of parsimony should be applied to give less credence to baroque theories. I see no reason to place the frontier of "what happened right at / before the Big Bang where vanilla GR breaks down" in a different epistemic category than all other frontiers of science, as the blog post seems to do. i.e., I see no reason that we should not build models and collect data in order to expand into this frontier, as we profitably do in other areas of science.
