At The Guardian we had a pretty direct way to fix this [the problem of zombie feature flags]: experiments were associated with expiry dates, and if your team's experiments expired the build system simply wouldn't process your jobs without outside intervention. Seems harsh, but I've found with many orgs the only way to fix negative externalities in a shared codebase is a tool that says "you broke your promises, now we break your builds".
