Why does laravel use closure in routes by default?

As you know using route closures prevents caching, and it always bothered me why does Laravel include the following route by default (which prevents route caching):

Route::get('/', function () {
    return view('welcome');
});

Instead of simply using:

Route::view('/', 'welcome');

Is there a downside to using the second method? or are they the same?

I know I can simply edit it, but just want to know if there is a specific reason for this.
