Yeah, but at the end of the day the different video settings still use "standard" formats that a normal consumer can open on their desktop or laptop. HEIF being the real outlier, changing any of the settings buried in Settings.app for the built-in Camera.app doesn't effect the ability of a normal user to view their content on a current operating system (Windows 10 or macOS High Sierra). RAW images change all of that - Windows 10 has really basic support for some RAW formats, and there are some workarounds like RAW+JPEG in ProCam but it results in two separate files combined as one "image" in your iCloud Photo library, syncing this to a Windows PC results in two files and just confuses users (macOS works around this by hiding everything in the Photo Library, invisible to most users).
