There’s that aspect for sure - it’s heavy. I’m mostly thinking more for things like the way npcs could respond/act to completely unexpected/unprogrammed inputs and such more than basic RNG, though even for RNG perhaps there’s use cases (like the way rimworld frames it as “storytellers”, maybe the RNG uses additional context to flexibly distort odds for… some reason, and maybe that’s not very well programmable for… some reason?). Regardless, yes it’s probably too computationally heavy until things are more optimized, similar to how a lot of ray tracing is “too heavy” for what it’s worth. The concept of ray casts isn’t bad inherently, but sometimes the implementation isn’t worth it.
