Complex classes like Tx_FeatureFlag_System_Typo3_TCA often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes.
Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.
While breaking up the class, it is a good idea to analyze how other classes use Tx_FeatureFlag_System_Typo3_TCA, and based on these observations, apply Extract Interface, too.
