It would be nice to be able to optionally sanitize photos I share with someone. I do want my own photos to include the full metadata available, and sometimes I do want to share that with someone. But sometimes I want to share a photo with someone and I want to know they are not holding onto all the metadata my phone included with it. So it would be nice if sharing photos with someone also had an option to share a version of that photo that has the metadata sanitized.

This seems to be a very important issue, as this directly impacts the privacy of the users using photos and the sharing feature.
