I'm beyond excited to share with you all that tidymodels now have sparsity support.
We now support sparse data during the whole process, generate data sparsely in recipes steps when your model supports spare data structures. and you don't have to change anything!

Improved sparsity support in tidymodels
The tidymodels ecosystem now fully supports sparse data as input, output, and in creation.
