Most image sensors are not square, they are 4:3 or 16:9. Square sensors are typically used for more specialty applications.
I agree it could be useful on a phone to have 1:1 sensors, but I would still support the direct recording to standard video resolutions and aspect ratios as otherwise encoder limitations will affect what video you can shoot.
The image sensor is square… it should just shoot 1:1 scale and let you crop it to an orientation later
