How to properly replace ServiceLocator in ZF3?

Question

Zend Framework

Good day!
When upgrading from ZF2 to ZF3, a ServiceLocatorAware deprecation error appears, since I use ServiceLocator in the controller, in services. Here is one example of solving this problem - to make a factory and specify dependencies in it. Everything seems to be logical.

// Класс фабрики
class IndexControllerFactory implements FactoryInterface
{
    public function __invoke(ContainerInterface $container, 
                     $requestedName, array $options = null) 
    {
        // Извлечь экземпляр сервиса CurrencyConverter из менеджера сервисов.
        $currencyConverter = $container->get(CurrencyConverter::class);
        
        // Создать экземпляр контроллера и передать сервис в его конструктор.
        return new IndexController($currencyConverter);	
    }

Please explain what should I do if the controller has about 10 dependencies? All to push in the designer? It's not very clear after using ZF2.
Let me give you an example, I have an order management controller, it has mappers (I don’t use the doctrine) Order, Tabular part of the order, Discounts, Counterparties, Contracts. As well as services - work with 1C and sending messages to the mail.
If you remove the ServiceLocator from the controller, you need to create private variables for each mapper and services, then create a constructor in which to insert the objects received from the service manager.
To what size can a constructor grow? Not all mappers and services are used in every action, why do I need extra?
All googling on the Internet comes down to a simple example of one dependency, and how to use not a word in large projects (

Separate classes and dependencies. Otherwise, slide down to the magentoo level.
The controller shouldn't have that many.

To what size can a constructor grow?

1-3 external services, except for technical ones (like loggers, transfers, etc.).

how to use it in big projects

SRP.
