I think it would make a lot of sense to have a dialogue popping up in a scenario where a user does NOT approve of a deviation in their favor. I.e. there is a negative deviation that they are rejecting. Similar to how we have a dialogue asking the user if they really want to push an order based invoice past the Connect step.

I cannot think of a whole lot of scenarios where it makes sense to not take the more favorable price given by the supplier, but there might be some. Tolerances would not always have these go through automatically, and it makes sense to guide the end user to not make mistakes.
