Do you switch off Sim Culling?

I switched off culling a long time ago. And I have a mod that stops random townies from generating, so every "NPC" is actually a sim that I made and played with at some point. I have 662 sims (living and dead) and I keep track of literally all of them. I like having that control.

I'm also never deleting any of my ghosts/rarely played sims because I don't want to ruin the family trees. Like, every singe sim in my game has someone on their family tree; there are no randoms.
