Not sure if there's a chance of this check getting longer, but maybe we could update it to use a single variable for the payment methods, like $is_immediate_processing_method.

$immediate_processing_methods    = array_merge( WC_Stripe_Payment_Methods::VOUCHER_PAYMENT_METHODS, WC_Stripe_Payment_Methods::WALLET_PAYMENT_METHODS, [ WC_Stripe_Payment_Methods::BLIK ] );
$is_immediate_processing_method = in_array( $payment_type_meta, immediate_processing_methods, true );
