Generally, after this release, the broom dev team will first ask that attempts to add tidier methods supporting a model object are first 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.mixedtidytextbroomstickbiobroomTo 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.
In the case that the maintainer is uninterested in taking on the tidier methods, please note this in your issue or PR.
