when should you consider a feature flag system

hey everyone, ive been thinking about feature flagging lately for a new project. it seems like a great way to decouple deployment from release, test new features in production, and roll back quickly if something goes wrong. but is it always worth the overhead? at what point does implementing a feature flag system become more of a burden than a benefit for a team or project? curious to hear your experiences and thoughts on when to adopt this pattern.
