Changes to the human-readable output of most standard Unix tools are a big deal given the amount of scripts which depends on them. They commonly are seen as fairly stable to the point that even some non-Posix tools like e.g. apt, which doesn't have a stable CLI warns about it to stderr if you try to redirect it's output to a pipe[1].

If anything, though, that's a good reason for a tool like this to exist rather than have every script that depends on these tools use their own, often hacky, parsing of the output.
