What would this use case be?

That would be very useful for some people.

One thing that might help, but it would absolutely need back
compatibility support (or a utility to do the conversion) would be to
store the pathname along with the JPEG in the thumbnail file, so it
would be possible to read the thumbnails even if the thumbnail index
file is corrupted.
