Summary: The generated Flow libdef for `babel/types` declared `duplicates` as a required parameter on `getBindingIdentifiers` and `getOuterBindingIdentifiers`. It is actually optional, both at runtime (only read as a truthy flag, defaulting to the non-duplicate map) and in the upstream TS types: https://github.com/babel/babel/blob/7.x/packages/babel-types/src/retrievers/getBindingIdentifiers.ts#L17-L36 This prevented legitimate single-argument use later in this stack. Separating it for export to RN + Metro. Changelog: [Internal] Differential Revision: D111056985
