Is this something which could be added to tiffcp permanently?
I think that there would need to be tiffcp options to select what metadata to transfer and that the default should be what it is currently in order to not cause harm to existing processing.
Metadata is sometimes tied to pixel content and it is possible that using tiffcp might cause some transformation which invalidates part of the metadata.
