✅ Alternativas modernas a los overrides

<?php

// ANTES (con override):
// class Product extends ProductCore {
//     // ... añadir campo al formulario sobreescribiendo metodos
// }

// AHORA (sin override, usando hook):
public function hookActionProductFormBuilderModifier(array $params): void
{
    $formBuilder = $params['form_builder'];

    // Añadir campo al formulario de producto
    $formBuilder->add('my_field', \Symfony\Component\Form\Extension\Core\Type\TextType::class, [
        'label'    => 'Mi campo',
        'required' => false,
        'data'     => $this->getFieldValue((int) $params['id']),
    ]);
}

// Para el pedido:
public function hookActionOrderGridDefinitionModifier(array $params): void
{
    $definition = $params['definition'];
    // Modificar el grid de pedidos
}
