Yes, but certainly you can see how even a toy example with just 4 booleans is already getting complicated?

It's certainly complicated. But not WTF-level complicated.

Complexity is both subjective and relative. Allowing invalid states in your model is going to complicate things, too.

I wouldn't mind having this example in production. It will scale just fine with the number of booleans.
