I would assume you could create a history from the entire set of archived tzdata* files.  That would be a one-time activity, and if any manual adjustment is needed to deal with oddities in old files, that wouldn't be a problem because it would not happen again.  Then as each new release comes out, it would be one more delta.

Presumably the tzdist master would go to the IANA tz repository for this, and all the mirrors would avoid bothering IANA and take from the master.
