The danger is, that you end up passing the decision model something where the choice is trivial. There's so much in the harness that you don't need any intelligence.
I've seen way more about how brittle and inconsistent Jev is with decisions that should be straight forward, like from pokemon...
- I'd like to buy a potion!

- I'd like to buy a potion!
- Are you sure?
- No...
- <repeat for 5 minutes>
it took it waaaay too many tries to buy item
Then there are the examples like coin flipping or dice rolling, Jev doesn't understand basic probability, picked heads like 84% of the time or something...
