GIMP can't warn about losing metadata if it doesn't know whether such
metadata was present.

Having said that, libtiff3 includes the tiffinfo program which is able
to display XMP and EXIF metadata from the tiff files I tried. So in fact
I think it's the tiff-load and tiff-save file plugins that might be
waiting for someone to write a patch to support metadata.
