Even if they could do it thru built in tables and without a network connection, I am sure companies don’t want to be in the business of having to release firmware updates for DST adjustments, which do happen pretty often around the world. Especially firmware updates many years after the camera has been released.

One problem with having a built in table that may go stale is that your camera will change the time when you are not expecting it.

Exactly this! If you look at https://www.iana.org/time-zones you can see that in 2022 there were at least 7 changes that caused a release of the tzdata files.

The example that comes to mind is Turkey in 2015, where they moved DST 2 weeks later, with little to no forewarning, for election shenanigans: https://www.bbc.com/news/world-europe-34631326

I hadn't considered the complexities of the world market.

However: do you change the time settings in your camera when you cross time zones? Do you care if your EXIFs are tagged with the correct local time?

I wonder why the standard isn't set to Zulu time. As long as the camera's clock is set correctly with respect to that, the time tag would be accurate regardless of locale. (If memory serves, Microsoft Windows files are tagged by Zulu time. The time and date displayed in Windows are those of the PC's time zone, though.)
