No these are not basic features, most users don’t really care about it. You don’t think Apple does research? How can Apple have such an huge market share if those things are things that people are desperate for like you act? And no, I can’t take a full camera on my backpack trips, every ounce counts. Plenty of people shoot with their phone, don’t act like you don’t know this.
Yes, plenty of people that don’t really need high quality Dolby Vision HDR pictures shoot with their phone. It is not a lie to say that they’re really late on a lot of things, such as sideloading (they’re still trying to push this back lol), simple customization options, ability to use a different web browser than Safari and much more. You sound like the fanboy here.
