If for some reason you want to end up with a 1:1 image, you can just crop it after. But you'll still have the complete picture in case you want to crop it again differently later.
I just object to getting rid of information before I absolutely need to. You can never get it back.
This is an essential principle, no doubt about it but we are talking convenience at the moment of capture with a mobile phone camera. Some people though would be keen to post-process mobile phone photography and apply the rule you mentioned, others may not deem it necessary. In order to confirm the validity of your post, I will provide a personal example: my best photographic achievement to date is exactly a 1:1 photo. When taken, it was of course a RAW data, 2:3 ratio, i.e. the "golden rectangle", then I cropped it to 1:1.

Generally speaking, the Passport provides adequate output even after the loss in 1:1 mode.
