As an electrical engineer (I'm assuming you're one - correct me if I'm wrong), have you ever designed a hardware product where certain requirements, constraints, and goals were imposed? There are always tradeoffs and they are usually multi-dimensional.
"only that you and one or two other commenters don't know how to accomplish it."
Well, OK, feel free to weigh in with your recommendation for a camera/sensor recommendation and design that would work. And please take a look at Post #43 where an engineer who designs camera/sensors for phones and laptops weighed in. That'll give you a good head start. Should be easy for you.
I appreciate what you're trying to do, but after a while, you just have to realize that some people just can't swallow a reasonable explanation, and the only thing you're doing is hurting yourself by wasting time with them.
What I find fascinating is that people take so much for granted, as if a regular 2.25X improvement in resolution is some kind of birthright. Will it happen? Of course it will! Will it take a lot of pain and money to make possible, given the constraints? MASSIVE AMOUNTS OF PAIN AND MONEY.
I know, I've been there. For a small company, hundreds of millions of dollars in investments, over a decade of time, fundamental process improvements, new chemistry, months upon months of working 110 hour weeks, sacrifices, you name it. And heaven forbid if it doesn't show up quickly, lest some internet fart with a dog avatar (or the equivalent in "tech journalist") sneer at you.
Don't worry people, improvements (most probably, I don't work at Apple...) are coming, (I'm guessing) whenever they re-do the laptop lid design. They have to create a way of getting 2.25X the data from the camera down to the motherboard. They need to pull a rabbit out of the hat and figure out how to make better optics in that limited space (to compensate for 2.25X less light per pixel), and/or get a sensor that's 2.25X more sensitive, and/or sensor technology that can handle simpler, flatter optics. Or make a deeper lid. (You never know, supposedly new display tech like mini/micro LED backlighting may cause major changes, and new trade-offs for everyone.)
It all can be done, it is just a pain. In the meantime you got a massive win with the M1 chip, which also was a life-consuming and expensive pain to produce, SO BE HAPPY. If the gripers would try creating such improvements themselves, they might gain some perspective.
