Feature Flags Without Permanent Complexity
Feature flags let teams separate deploying code from exposing behavior. A change can reach production while remaining disabled, then be enabled for internal users, a small percentage of traffic, or a selected customer group. That flexibility reduces release risk, but every flag also creates another possible execution path. If flags are added casually and never removed, the codebase accumulates conditional behavior that becomes difficult to reason about and test. The engineering goal is therefore not to maximize the number of flags. It is to use flags as temporary control points with explicit ownership and a planned end state.
