There is something weird about wanting a 16:9 sensor when it's not the industry standard. We're talking about photos here, not videos. As stated earlier, OP can crop his photos to 16:9 if he wants, but it's less effective than just simply using Panorama if he wants a wider image. The camera will always crop out part of the image to make it 16:9 since the sensor is not 16:9.
Also why would one want the camera to choose what part of the image to crop out to make it 16:9 when you could crop it yourself and choose what area to crop? I'd rather the latter, than the camera decide for me which part to cut out.
Perhaps you should read through the topic and replies at hand next time before jumping to conclusions.
Nobody is asking for a 16:9 sensor. You're making stuff up. He wants to take 16:9 photos.
Again: Apple provides the 1:1 option, but completely ignores 16:9 (which is much more useful). You actively seem to try to avoid this fact, as you're not responding to this.
Also, the camera is not choosing what part of the image to crop, you're doing that yourself when you're taking the photo. It's just easier to take a 16:9 photos than to crop it.
You're reasoning is flawed. You don't seem to be able to understand that not everyone is like you, and some people actually have normal reasoning that makes sense.

Same can be done with the square version and yet that option has been added to the camera app. So LOL indeed.
No one seems to understand this.
Cropping a photo takes a lot more effort than taking a 16:9 photo. If you want to take 16:9 photos only, you'd have to edit +/- 100 photos after a holiday or something. Real fun job yes.
Also, who cares about "cropping the sensor" - you're framing the image when you're taking the photo right? Really guys, stop being so narrowminded.
