There are plans for full history dumps.  In fact osmosis (which produces 
the existing diffs) can already produce full history diffs but they're 
not enabled at the moment.

The current minute changesets have a problem where they occasionally 
miss data.  Once we get this ironed out I'll take another look at full 
history diffs.

Some sample data is available here:
