Would it make sense to have a separate "update" process, so the parser
in the loader will never have to deal with legacy files?
When the user opens a file with a lower version number, we branch into
an update wizard that handles updating the file, rewrites it as the new
version and then restarts the load process.
This way we could also keep the schematic element rescue outside of the
loader code.

Hi Simon 
I'm opposed to any program that modifies a file when I open it. In my opinion the file should only change when I press the "save" button.
Also, there could be valid reasons why somebody has to run an older version of the software, or keep their files on the older version of the file format. Maybe they use a custom parser to interface with for instance a laser engraving machine, that cannot handle the newer file format.
