This is one of the reasons we built type-safe feature flags at Hypertune. When a developer deprecates a flag, they get type errors everywhere it's still used. This fails the build so they're forced to remove all the flag references, and they get a nice IDE / compiler driven workflow to do that. Otherwise it's easy to leave flag usages around.
