After the release of broom version 1.0.0, the broom dev team now asks that attempts to add tidier methods supporting a model object are directed to the model-owning package. An article describing best practices in doing so can be found on the {tidymodels} website at https://www.tidymodels.org/learn/develop/broom/, and we will continue adding additional resources to that article as we develop them. Some additional packages that supply themed tidiers are:
broom.mixed
tidytext
broomstick
biobroom
To aid in the process of writing new tidiers, we have provided learning resources as well as lightweight dependencies to re-export tidier generics on the {tidymodels} website.
