This is a good point, and in some cases in hindsight I went too far in 
merging zones that were coincidentally the same (e.g., merging 
Antarctica/Syowa with Africa/Nairobi), so I'll undo those changes soon. 
  However, in many cases the relationship is not coincidental, as we're 
talking about most-likely-invented data from a single source, and for 
these cases we can safely discard the spurious data.

This is not a question about optimizing the implementation; it's a 
question of having the tz data reflect our knowledge as accurately as 
the current format allows.  Currently the tz database pretends to know 
more than it does, and to the extent that we can make it more honest and 
accurate we should do so.
