Laravel Clockwork middleware dumps a ~120kb json into laravel_app/storage/clockwork on every request (196946 files and counting)

I wouldn't rise this ticket but yesterday by accident I saw that my storage/clockwork contains (fasten your seat belt):

19,490,265,152 bytes (19.92 GB on disk) for 196,946 items

Almost 197k of JSON files.

The problem can be solved temporarily by calling php artisan clockwork:clean. It does clean that junk but once I will refresh the page, new JSON is being created.

Another solution is to comment the Clockwork middleware in Kernel.php

public function __construct(Application $app, Router $router)
{
    if (env('APP_ENV', 'production') === 'local') {
        // $this->prependMiddleware('Clockwork\Support\Laravel\ClockworkMiddleware'); // <--- this
    }

    parent::__construct($app, $router);
}

but that's not the way how I would like to deal with that issue. In terms of the content of those files, it looks like a dump of request, db queries etc. I assume it's useful when using Clockwork in Chrome Dev Tools to preview queries or that sort of things but shouldn't this directory be auto cleaned etc.?
