You can't just go by time zone names because there are weird exceptions, like most of Arizona not doing DST. Then there's Indiana, which didn't do DST until 20 years ago, and there are some counties that switched time zones when the DST law took effect... if you're in one of those counties will you just accept old timestamps being an hour off? Granted, this gradually becomes less of an issue the further we get from the change. But nothing guarantees that there won't be further changes in the future.

And that's just the US, there's almost 200 other countries each with their own laws.

There are guarantees that there will be changes in the future! There are changes regularly, some expected, some not. In some countries the suspension of DST due to Ramadan is decided on the first night of Ramadan itself when a group of elders look at the moon and decide whether Ramadan starts tonight, or tomorrow.
