I think ripgrep specifically is counted in the comment you reply to as a tool that _does_ do one thing well, and that one should use it (or grep) in combination with an ls, instead of giving ls filtering abilities.
I suppose. But I wanted to point out that ripgrep couples functionality, specifically in contradiction to the Unix philosophy. And actually, many command, including "traditional" tooling, so as well.
The point is that many pay lip service to the Unix philosophy as if it were an end. But it isn't.
