I agree about the lawyers to a certain extent. However, my engineering background tells me that there should be at least one method of retention to prevent a worst case scenario. In my case the rear bolts had none! The Shimano bolts come with Loctite applied and this should be enough to keep the bolts from falling out. The clips and pins are the second level protection to satisfy the lawyers.
