I'd probably still have serious reservations. As the argument from apparent design does not prove the existence of a designer, so the argument of the primal shout does not prove the existence of the shouter. There are lots of possible reasons why there might have been a compressive wave disturbance in the inflationary era, just as there are lots of reasons why there might be disruptions in, say, the perfectly smooth cyclone action you might see in a perfectly circular sink containing perfectly still water when you open the drain. Consider Bode's law of planetary formation: the universe does not guarantee that that which is placidly homogeneous will stay placidly homogenous, even in closed, uniform, homogenous systems in dynamic equilibrium.
Indeed, I would expect the official reaction to be bucketing the observation into the Anthropic Principle rather than attempting to personify the origin.
But with regard to the meaning, the MAXIMA, BOOMERANG, and DASI collaborations made it clear that the structure of the universe is due to inflation, not to topological defects. Cosmological Patterns and Galaxy Biasing (pdf)
And from Berkeley Lab:
Had the structure of the universe been seeded not by inflation but by topological defects, that is by phase changes in the extreme energies of the early universe, the first peak in the CMB power spectrum would have been broader and lacking harmonics.
