I think it can be done at the UI level from now. A good illustration is
like I did it for Nautilus.

Actually the reconcile take the Exif, IPTC and XMP and merge everything
together. Exempi does it if it handles the IO (which it does not yet).
Typically, loading the XMP is there is none in the file would lead to a
XMP metadata block with the Exif metadata in it.

Something like that. Note that the orientation don't need to be
displayed as EOG auto rotate.
