> Did that thing that basically no one will ever see need to be created over the course of 9 months?

As an engineer, I worry so much about writing perfect code even when I know it is temporary script for one off job. In my home, I painted top of the doors that no one will see. But I know it is painted.

It is nice that people care about these small things.

There's a difference between caring about the small things and caring about things that don't matter at all. Look at city skylines 2. Every tooth in every person is individually rendered. Why? Every house hold budget is tracked and managed. Even though you can't do much about it.

Lots of technically advanced simulations are going on in that game to build the most advanced simulation. But people don't play a game became its simulating a city accurately right down to individual teeth in every citizen. They play a game because it's fun.
