That's a fallacy, I'm afraid.
We don't know if their formats are crazy.
But they certainly appear to be undocumented. Until they are
documented, or someone reverse-engineers them, we are unlikely to gain
support for them in open-source software.
(OTOH, it could just be attached in the metadata. EXIF / IPTC support
is not complete yet.)

These could be quite helpful if someone is inclined to reverse
engineer it to spot the difference
