`Categorical.to_list` is the only one that we may want to deprecate the other way instead? xref https://github.com/pandas-dev/pandas/issues/14278 https://github.com/pandas-dev/pandas/issues/8826 w/r/t to_list/tolist i dont have an opinion, just dont want an outlier.  (also i dont expect people to use Categorical directly that much) Yeah likewise. I would just recommend tabling `Categorical.to_list` until there's some more steam around which to list variant we want everywhere. sure, will update updated + green, will handle Categorical.to_list in an upcoming DEPR PR Thanks @jbrockmendel
