From the comments I see that there are some different coreutils implementations out in the wild, mostly done for fun. I am very happy about this. This means that there is not much energy put into implementing new coreutils features or fixing bugs. I think this is good. This means they are more or less finished. Mature. Software that is done and usable. That is something outstanding. This is an example of software that does not need to be in an never-ending flow of changes, not because it is abandoned, but because it is finished. I think we need more of that.
