Due to another related project, this repo is no longer being actively maintained. Shall we consider removing it from the import list?

Very unexpected. I thought that project had good traction. I guess we can remove it then. But I wonder if we should just let it be for now for people who want to migrate from it to Restfox. We can remove it in a few months.
