Problem is you are advocating that just because you don’t need feature x no one else can have it. Even though adding feature x won’t impact you in any way. That’s a straw man argument.
You have it backwards.
It's not that I don't need nor appreciate those features, but that I have come to terms with the way Apple does things, and made my peace.
A little bit of personal history (skip ahead if you aren't willing to tolerate me in self-soliloquy: I got my first iPad in 2012, and started using it in the classroom. Peer-to-peer airplay would be supported in 2015, while 2016 saw the release of the iPad Pro and Apple Pencil. In the meantime, the iPad got incremental updates which improved its utility in teaching. Sometimes in dribs and drabs, sometimes in leaps and bounds. Today, I would say that my iPad setup is more or less complete. Could Apple do more to improve its functionality, such as support for third party drives? Sure, but I am not going to lose sleep over missing these features, and I will get around to using them if and when Apple does finally get around to supporting them (if at all).
In another vein, could those aforementioned features have been supported sooner? Sure. Earlier peer-to-peer airplay would have saved me the hassle of carrying a pocket router with 4g dongle around with me to work with my Apple TV. But it is what it is. If Apple doesn't (yet) support a certain feature, I will just live with it. And when they (finally) release a feature, I will use it if I find a use for it. When those features were finally released, I wasn't angry or mad that Apple took as long as they did. I simply went "cool!" and made use of them.
For me, what I have come to accept is that neither platform is perfect, and the fact that I have opted to stick with Apple all these years means that I ultimately value what Apple does offer me over what it doesn't (and over what the competition promises). Part of this also means accepting, embracing the fact that Apple will always be Apple.
What this means is that Apple marches to their own beat and doesn't care a crap about what everyone else thinks. That's what makes them so awesome in my book (and admittedly so very insufferable to others). But on a more serious note, Apple isn’t a very difficult company to read. You just have to block out a lot of the noise and bullcrap that you see online and mostly look at their design decisions and listen to what they actually say.
And so I chose to embrace the Apple ecosystem in its entirety. For example, when Apple released the AirPods in end 2016, I bought them right away, even though my iPhone 6s+ still had a headphone jack. Because the writing was on the wall. Apple has optimised their product around a certain vision of how they would like you to use it, and I felt it was simply easier to embrace this so as to maximise my user experience, rather than try to fight the change (eg: continue using an adaptor with wired headphones, or hanging on to your 6S+ for dear life), and making yourself so bitter and miserable in the process.
Which is why Apple is so polarising. They are precisely the sort of company who would ditch something so users have less choice, but possibly (in their opinion) a better experience. More often than not, Apple will aim for product experience at the sacrifice of user choice. And if Apple's idea of what you want in a product matches yours, then it is full of secret magic and delight. And I guess I have been lucky in that Apple's design decisions in general have been more or less in sync with my own needs and desires.
And if not, it can be frustration, like jogging through quicksand. You can try to fight the system with every ounce of strength in your body, but it will be pointless, and you will ultimately die a painful and agonising death.
It takes a great deal of courage to see Apple in all its tainted glory, and still love it.
And if you have it thus far, thank you for your patience in listening to me rant and letting me get this off my chest.
