[Question] Why is R4 support disabled on latest version (0.5.6)?

Description of Issue

I've tried to use the R4 version functions from PySpark but it seems it cannot find the java classes for R4 on the jar. I've checked the project code and it seems that the R4 module is not included.
When I try 0.4.6 version, R4 functions are present and working.

It will be support for R4 in the near future? Why is R4 support disabled on the latest versions?

Is anyone still maintaining this? There haven't been any updates since 2020 so I'm wondering what future of this project is.
