While it sounds good on phosphor, the concept of code diversity is so 
abstract, compared to the significant operational challenges and 
associated security challenges of operating separate systems performing 
the same functions (sort of), but differently, that any potential 
benefit is generally outweighed by the negative impact to security 
posture of said challenges.
