Feature Flags Without Long-Lived Technical Debt
Feature flags decouple code deployment from feature release. A team can deploy dormant code, enable it for internal users, roll it out gradually, and disable it without rebuilding the application.
The cost is hidden control flow. Every long-lived flag creates another possible system configuration, and interacting flags multiply those configurations quickly.
The engineering goal is therefore not “use flags everywhere.” It is to make each flag temporary, observable, and owned.
