Only use this if you _must_ continue using `babel-loader` directly, but still want to customize.
 
-* `metadataSubscribers`: Default `[]`. Takes an array of context function names. E.g. if you passed ['myMetadataPlugin'], you'd assign a subscriber function to `context.myMetadataPlugin` within your webpack plugin's hooks & that function will be called with `metadata`.
