What about adding/editing some basic EXIF data

uploaded Commons files that support them, like jpg? They can be deleted by a
malicius user into downloads, but they will be saved when hotlinked. I don't
know if any EXIF managing is currently done on Commons files; IMHO it could
be useful, for a number of reasons, and not only for hotlinking.

EXIF data is fine, but it doesn't really suffice for attribution: No
on will find it; it's effectively not there.
Unfortunately all that metadata is currently stripped for any
thumbnails. So in the common case that they hotlink a thumb you don't
even get that much.
