A (binary searchable) table implies a flat two-dimensional structure. Zones and rules are more than two-dimensional. At the point when I resolve zones and rules into a linear table, I think I lose the efficient storage and need to write out the transition times for all years separately, which will be huge.
You can fit a table entry into four bytes, so for two transitions each year between 1970 and 2038 (136 entries) you need just over half a kilobyte.
