You can still chain ripgrep. I specifically designed it so that you can chain it just like you would a normal grep.

It does indeed also include other functionality that might traditionally be left to other tools (like filtering files). But this is nothing that GNU grep wasn't already doing itself anyway.

IMO, it's better to view the Unix philosophy as a means to an end and not an end to itself. And IMO, it's important to weigh the benefits of coupling to the user experience.
