Comment (by joemcgill):

 I ran a few tests and it looks like at least iOS and OS X are reading the
 orientation from the Exif profile and not the properties, so I don't think
 we can strip Exif profiles until after we've handled orientation. In the
 mean time, [attachment:28634.7.diff] protects icc, iptc, and exif metadata
 unless overridden by a filter. This would allow people who don't care
 about any of the metadata to strip everything by doing something like:

 {{{
 add_filter( 'image_protected_profiles', function() {
     return array();
 } );
 }}}
