Here's a recent (2021) paper on the idea: https://arxiv.org/abs/2105.08719

It has the nice feature of explaining why the density of baryons and the density of dark matter are not too different. Naively, there's no reason to expect the two to be anywhere close to each other. It also offers an explanation for the observed matter-antimatter asymmetry in the universe.

Don't believe any theory until it's been well tested.
