Why was it retired? Are there any follow-up projects like this?

I see this repo is in the attic, I see that it is labelled as retired but I cannot find any discussion on why it was retired and whether there are any other approaches that enable using widgets in IRKernel (I came here from IRkernel/IRkernel#430). Could you please add a pointer in the readme explaining the situation?

Yes PLEASE. We are looking at a system where having widgets in IRKernel would be extremely useful.

Alternatively, is there at least a way to invoke Python widgets via, say, reticulate, and just have IRKernel display them and return a small data structure containing their state to the R code to control some R code?
