I think the idea of anonymous classes is very useful.

a use case that I recently encountered, is to override a specific method in
a class.

So instead of creating a new class that extends the original class, you can
just use an anonymous class and override the methods that you want.

E.G.

You can to the following:

use Symfony\Component\Process\Process;

$process = new class extends Process {
    public function start() {
        /* ... */
    }
};

instead of the following:

namespace My\Namespace\Process;

use Symfony\Component\Process\Process as Base;

class Process extends Base {
    public function start() {
        /* ... */
    }
}


$process = new \My\Namespace\Process\Process;
