      > ReadPreference.fromOptions({readPreference: 'nearest', readPreferenceTags: [], hedge: {enabled: false}})
ReadPreference {
  mode: 'nearest',
  tags: [],
  hedge: undefined,
  maxStalenessSeconds: undefined,
  minWireVersion: undefined
}

      This seems like something that should be allowed according to the typescript definitions, and was reported as a bug to us because it breaks hedged read settings in mongosh.
