True ... as long as those older tarballs represent data that our current
workflow can process. For instance, if we did another documentation
format change (from XML to something else), the older tarballs would
perhaps no longer be useful for this purpose.
On the other hand, it's hard to believe that we'd make such a conversion
without tools to help. So probably if the situation came up, we could
cobble together something that would allow ingesting the old format.
