To be fair, everything that astrophysics comes up with will be massively under constrained. For all intents and purposes we work with a single datapoint and try to infer dynamics.

If a very small detail of space-time, i.e. stochastic behavior at the Planck scale, results in an emergent effect that explains something on the cosmological scale, that is explaining a lot with a little. Stochastic might not even mean random or non-deterministic (as I understand - and as the paper suggests, i.e. non-quantum), it could just be chaotic. Which would be very parsimonious. So many seemingly different effects we observe are the result of very simple things, under stochastic, statistical, entropy, thermodynamic type situations.
