I'm pretty sure if signing images becomes the norm, because cameras will do it automatically then social media sites etc will start to care - or at least be thankful for the additional metadata.

EXIF already includes extensive metadata, including phone model and GPS location. For professional cameras, there is often camera and lens serial numbers too.

This has been the case for many years, and so far social media sites never care - they strip that info instead. Why would this change with one more extra piece of metadata?
