What would our own asteroid belt look like from a few thousand light years distance? It would seem pretty fuzzy. Also demonstrates that such structures can be self maintaining.

I'm not sure this article really says anything. Maybe some solar systems are such that they never form planets. Wait another 200 million years and they will still be in the same state.

I'm not convinced this says anything about the development of planets at all.
