Perhaps the thinness of the gun dictated a non-conventional rail? Even though I use rail-mounted lights on some of my guns, for a tiny concealed gun, I don't feel I need a light. Once someone puts calipers to it, we shall see if the non-conventional rail was dictated by the gun's small dimensions or not.
As for the drop safe, from the article, they stated that "SIG developed an entirely new, enhanced drop test protocol for duty handguns. They dropped the P365, 574 times in 26 orientations as well as five drops at 6 feet on concrete. For those of you are wondering if this new test protocol is going to be retroactive to older pistol models, it isn’t. However, any new models will be subjected to this protocol during development.
Additionally, they’ve put over 40,000 rounds through a P365 with no frame cracks."
The author did have failures while shooting in the cold they attributed to lube, but that will be something to keep an eye on (when the gun was cleaned, it worked perfectly, but...).
