By now we've gotten several projects that re-implement a core unix util in a safe language, often also with better performance due to concurrency, better standard primitives, etc Have any of these ever been adopted by a distro as the default implementation? Is that something that might happen? I.e. I would never bother to upgrade my sudo command or my grep command, but getting better defaults would be better Obviously they would have to be perfect drop-in equivalents, which some of these projects don't try to be, but others of them do
