Thank you Harris. I think I made my idea clear about the need of a lighter approach.
Thank you Paul. I hope the future reviews on this can create simplified structures for us all.
To be clear, any “lighter approach” or “simplified structures” will most likely take the form of an additional file, as Paul described below. It will almost certainly not involve removing any timezones (or “tzdb regions”) from the database. -- Doug Ewell, CC, ALB | Lakewood, CO, US | ewellic.org
On my long list of things to do is coming up with a table that would let users do that more easily. It would be like tzdb's current zone1970.tab, which partitions the world into zones where clocks have agreed since 1970; however, it would partition the world into a smaller set of larger zones whose clocks agree now and are predicted to agree in the future.
This would be something along thne lines as you suggested, as people in Brazil would have just four zones to chose from in this new table.
