It doesn’t really matter how you manage changes to feature flags, but using version control gives you a couple of nice benefits:
* gives developers the opportunity to describe their change
* let’s you roll back a problematic patch
* blame and bisect problematic patches
Ideally, you should also be able to see your feature flag changes in prod much faster than it takes to cut a release. You need this in order to be able to quickly roll back bad features.
