> We have some rules that are tricky to adhere to such as 
> ExhaustiveSwitchHasDefault because the enums they operate on come from 
> upstream nifi-api repository, which should be decoupled from nifi. If a 
> developer wants to add a default to an exhastive switch, it is good defensive 
> programming because a bump in dependency for nifi-api could result in a 
> switch statement that was previous exhaustive no longer being exhaustive, and 
> if there is a reasonable default, that is preferable to having to make code 
> changes every time the api changes.
