Comment (by juliobox):

 @alex: You can not strip exif by default since now. Also, my filter is
 only in the imagick class, so if not installed the filter won't be
 triggered ;)
 Imagine all photographers, already using exif data, maybe from thumbs, you
 don't know.
 Then, after the patch, all is gone!? They have to apply a filter to
 retreive exif like before?
 Not logical! Even if it's logic to strip it for thumbs, you can not do it
 by default from now, too late.
 @marko: new patch added, tested like that, works:

 {{{
 add_filter( 'keep_image_exif', 'exif_if_size', 10, 2 );
 function exif_if_size( $value, $size_data ) {
         return $size_data['height'] >= 500 && $size_data['width'] >= 500;
 }
 }}}
 If any of the sizes are < 500 px, the exif data will be stripped.
