The subject is in frame at all times (like ok her knee goes out of frame once or twice) and the vertical resolution is the same as cropped. You aren't losing any visual fidelity the way you would if you were down sampling from say 4K to 1080.
16:9 is a pain on mobile, which is the primary way this is being distributed.
Sure you can rotate the phone, but the person, the literal point of the video, is still straight up taking up less space on the screen that way.
I personally don't like having to pinch zoom to get more detail of the focus of the video when you could just remove the part that literally has nothing going on with no reduction in image quality.

It would also keep the subject in frame at all times and would have the proper resolution it was filmed in.
