I think the information stated in the deriving-data-selectors Readme file is outdated: https://github.com/reduxjs/redux/blame/735b5e2e173755b70ccdb02f37c8abfd827b2531/docs/usage/deriving-data-selectors.md#L256

Since reselect 5.0.0 createSelector uses weakMapMemoize by default. I think the behavior right now is still referencing the old lruMemoize.
