How to configure group of services by namespace in Symfony - php

Question

In the default Symfony 5 config, I looking this:
services:
...
App\:
resource: '../src/*'
exclude: '../src/{DependencyInjection,Entity,Exception,Migrations,Tests,Kernel.php}'
...
App\Controller\:
resource: '../src/Controller'
tags: ['controller.service_arguments']
It looks very cool. As if I can configure some default settings for a group of services by namespace, like that
...
App\Service\MySpecialTaskServices\:
resource: '../src/Service/MySpecialTaskServices/*'
public: true
... other default params\args for this NS ...
But this stuff not work: configuration loaded correctly, but parameters can not be applied.
May be I doing something wrong? It's bad idea, clogging services.yaml with a bunch of services with the same params.

I found a good reason, with using custom tags functionality. Maybe it help someone else.
Instantiate you services in group from single interface/abstract
Add _instanceof option in services.yml in global services: block
services:
_default:
....
_instanceof:
App\Service\MySpecialTaskServices\MySpecialTaskInterface:
tags: ['app.public_service']
Define a custom compiler pass for support you new tag with this process method
class PublicServicesGroupPass implements CompilerPassInterface
{
...
public function process(ContainerBuilder $container): void
{
$services = $container->findTaggedServiceIds('app.public_service');
foreach (array_keys($services) as $id) {
$definition = $container->findDefinition($id);
$definition->setPublic(true);
// other works with params
}
}
...
}
And register them in your kernel
class Kernel extends BaseKernel
{
...
protected function build(ContainerBuilder $container): void
{
$container->addCompilerPass(new PublicServicesGroupPass());
}
...
}
And this working correct. But I would like to make it easier.
