How do you name a type if it should be public/exported and the name should stand for: iPhoneX, iOS, eBay, etc.
Do you name them IPhoneX and IOS? or how do you name a type if the name in real world starts with lowercase letter?
You need to start the name with uppercase letter if you want to have it exported anyway, so I would say that your proposed names would be fine for cases in which you need such names.
