The problem is how to decide why the thumbnail has been
recreated. GIMP doesn't know why the user forced it.

program #1 wouldn't have to recreate. It could display the large
thumbs downscaled. The spec isn't clear if that's the recommended
behaviour but IMO it makes the most sense. The other way around is
more difficult.  An application using the larger thumbsize will
probably want to recreate the thumbnail if it only exists in normal
size.  Should it delete the normal sized thumbnail then?
