Is there a specific reason why we need to keep them different?

I think mistakes should be fixed when possible.

I guess we can change s3 (or s4) to automatically upgrade to the new
format (and maybe provide a script to parse the whole file system too).

We should really standardize on a fixed format as then other
applications (wine, freedos, and even GUIs) can then use the same

This is absolutely necessary to avoid bloat, and make this stuff useful.
Providing a common library with a liberal license to manipulate this
stuff would be a good thing too.
