Some of us don't want all of GNU's utilities; just on an as-needed basis. They're not as needed as they once were.
Many of these utilities have been rewritten in Rust and have more modern features and are faster.
For example, instead of ls, I use exa [1]. Or ripgrep [2] instead of grep. sd [3] instead of sed.
