-## Feature flags
-
-Feature flags are defined in `expressions/src/features.ts` (`ExperimentalFeatures` interface + `allFeatureKeys` array). They are plumbed through `ConvertOptions`, `CompletionConfig`, `ValidationConfig`, and `initializationOptions`. When a feature graduates to stable, remove its flag and make the behavior unconditional.
