I believe they've done more complicated physics in their game bitcraft, but that code hasn't been released yet (no idea if it will be.) But there has been work in the discord recently and 2 member have individually implemented rapier[1] at this point. I can't say anything about the related netcode however as I don't know how much they've focused on it. At the very least work has been done. The unity tutorial is just to get up and running as fast as possible in the simplest way possible, not to make the perfect decisions for a networked physics based game. I however do think they should provide an actual reference to prove the claim, [1] https://github.com/dimforge/rapier
