The new iPhone 14 sort of fits into this category of product. Just sort of, though, since Apple has redesigned the internals quite a bit to facilitate easier repairability, among other things. Plus, you do get new cameras and a few other new features. Externally, though, the iPhone 14 is essentially the same as the iPhone 13, and so is the core experience these devices offer. If Apple still did "s" models in their naming scheme, the iPhone 14 would probably be the iPhone 13s.
