Config/routes in cakePHP 4: is this the right way?

Need Help
1

I am new to CakePHP and in my Cake application I’am trying to integrate an API with versions (V1, V2 etc.). Is the routing in my config/routes.php with nested prefixes the correct way to implement versioning or should I use scopes?

use Cake\Routing\Route\DashedRoute;
use Cake\Routing\RouteBuilder;

$routes->setRouteClass(DashedRoute::class);

$routes->scope('/', function (RouteBuilder $builder) {
    $builder->connect('/', ['controller' => 'Pages', 'action' => 'display', 'home']);
    //$builder->connect('/', ['controller' => 'Pages', 'action' => 'display', 'homeobsolet']);
    $builder->connect('/', ['controller' => 'Start', 'action' => 'index']);
    
    // Admin
    $builder->prefix('Admin', function (RouteBuilder $builder) {
        $builder->connect('/', ['controller' => 'Users', 'action' => 'index']);
        $builder->fallbacks(DashedRoute::class);
    });

    // topics benennen, Bsp. /tagged/haushalt/garten
    $builder->scope('/ksentences', function (RouteBuilder $builder) {
        $builder->connect('/tagged/*', 
            ['controller' => 'Ksentences', 'action' => 'topics']);
    });

    // count topics 
    $builder->scope('/ksentences', function (RouteBuilder $builder) {
        $builder->connect('/hastopic/tag', 
            ['controller' => 'Ksentences', 'action' => 'topicstats']);
    });
    $builder->fallbacks();
});

/*
* If you need a different set of middleware or none at all,
* open new scope and define routes there.
*/
$routes->prefix('Api', ['path' => '/api'], function (RouteBuilder $builder) {
    //No $builder->applyMiddleware() here.
    //Parse specified extensions from URLs
    $builder->setExtensions(['json']);   
    $builder->connect('/ksentlist/{diff}', 
            ['controller' => 'Ksentences', 
            'action' => 'ksentlist',
            //'prefix' => 'Api',
        ],[
        'pass' => ['diff']
        ]
    );
    $builder->connect('/ksentcount/{diff}', 
        ['controller' => 'Ksentences', 
        'action' => 'ksentcount',
        //'prefix' => 'Api',
        ],[
        'pass' => ['diff']
        ]
    );
    $builder->connect('/testapi', 
        ['controller' => 'Ksentences', 
        'action' => 'testapi',
        //'prefix' => 'Api',
        ]
    );

    $builder->prefix('V1', ['path' => '/v1'], function (RouteBuilder $routeBuilder)  {
        $routeBuilder->setExtensions(['json']);  

        $routeBuilder->connect('/ksentlist/{diff}', 
                ['controller' => 'Ksentences', 
                'action' => 'ksentlist',
                //'prefix' => 'V1',
                ],[
                'pass' => ['diff']
                ]
        );
        $routeBuilder->connect('/ksentcount/{diff}', 
            ['controller' => 'Ksentences', 
            'action' => 'ksentcount',
            //'prefix' => 'V1',
            ],[
            'pass' => ['diff']
            ]
        );
        $routeBuilder->connect('/testapi', 
            ['controller' => 'Ksentences', 
            'action' => 'testapi',
            //'prefix' => 'V1',
            ]
        );
        $routeBuilder->fallbacks();  
    });

    $builder->fallbacks(DashedRoute::class);  
});

Thanks a lot for your advice!
