These systems are designed for the very common case of a global user base. If you have geographically centralized users, you can maybe do something simpler. That is rare in my experience - basically all of our customers have users worldwide. They typically don’t even know where their users are so making ux tradeoffs based on that feels really risky.

But maybe my experience is different than yours. One of the amazing things about the software ecosystem is how big it is. Everyone thinks their view is the common case.
