Such statistics were never gathered. I was told by the developers
involved that existing images with EXIF rotation would be very rare
and that most of them would be fixed by this feature, and I didn't
challenge that.

I think it's too early to focus on recriminations, we risk distracting
people from actually fixing the issue.
