Laravel Cashier: should I add a trial period in Stripe too?

Quoting Laravel Cashier documentation:

If you would like to offer trial periods to your customers while still collecting payment method information up front, You should use the trialDays method when creating your subscriptions.

Assuming I want to add a 30 days trial period to my subscriptions, I can create a subscription with this code:

$user->newSubscription('main', 'monthly')
        ->trialDays(30)
        ->create($stripeToken);

As a Stripe user, should I add a trial period in Stripe too?

I'm not sure to understand the logic of Laravel Cashier here. It seems redundant to declare something at two different places.
