I used my iPhone X un-cased for nearly two years based on that reasoning. My replacement is cased. And I've realized: regardless of how thick the phone is, people are likely to drop them, and give the materials nature of these things, a case is going to be required. So I'd rather start with something as thin as possible, given that I'm going to add a case either way. The end result is therefore as thin as possible.
