Then you must adjust your definition of "good": All commits that do not 
have the feature, yet, are "good": since they do not have the feature in 
the first place, they cannot have the breakage that you found in the 
feature.

That is exactly the situation in your original example! But you 
constructed the condition of goodness in such a simplistic way 
(depending on the presence of a string), that it was impossible to 
distinguish between "does not have the feature at all" and "has the 
feature, but it is broken".
