> Officially supports Exif data

Probably the best news here. While you already can write custom data into a header, having Exif is good.

BTW: Does Exif have a magnetometer (rotation) and acceleration (gravity) field? I often wonder about why Google isn't saving this information in the images which the camera app saves. It could help so much with post-processing, like with leveling the horizon or creating panoramas.

Yes, but websites frequently strip all or almost all Exif data from uploaded images because some fields are used by stalkers to track people down to their real address.

That reminds me when I first uploaded a picture to some forum and it showed my full home address together with a map as a "feature"

It is a feature because now you are aware of what you are sharing and can potentially delete it before too many others see it.
