It does track history, but not in a format that is immediately accessible.

Old data can be useful. Point in case, I may change GPS coordinates in
EXIF data and correct timestamps based on that info. Maybe I will even
correct white balance, etc. Still, I would want to keep full history
forever in _some_ repos. Basically my backup server and the main
desktop. All the rest would have up-to-date copies, only.
