It maintains the same temp, even when hot water temp or pressure is changing

I can’t speak for everyone but here’s what mine like like:

It doesn't even need to be that fancy. Basic ones will just react to reduced flow on the hot or cold side by reducing the other side proportionally to keep the temperature roughly the same.

Ah, called a thermostatic valve here I think? Maybe?

Did I live under the bottom of a well or something?

That's a thermostat and won't do you any good if the plumbing is set up in such a way, that all outlets are connected in series. You need a parallel approach (manifold with large diameter branching off to all outlets).

Maybe you've just happened to use hardware that was installed a while ago? Or you're in an area that's more traditionalist. I suppose there could be many reasons. Those are arguably also a little more expensive, so that could also be a reason.
