Review comment:
Just 2 cents, educating the users harder can be done in any way
(regardless of the default value), and imagine the education doesn't work,
deterministic by default would be much critical on the impact. (we can't trade
off correctness and performance.) I'd in favor of consider it non-deterministic
by default.
