in practice it has turned into something different: it is now primarily a way of supporting two versions of tzdb, the default one (which attempts to avoid politics as much as possible) and the backzone one (which instead attempts to avoid changes from older versions of the database).

As a reminder to everyone interested, it doesn't have to be this way. The "avoid politics" data is a subset of the "avoid changes" data. It would be a hell of a lot easier to model it that way (ie. with the source data being *all* the available data). Stephen
