loadDefinitions → loadDefinitionsFromConfig in Nette 3.0

Hello,
I'd like to ask: does the loadDefinitionsFromConfig changed its behaviour from previous loadDefinitions?

I'm trying to upgrade these lines to Nette v 3.0:

https://github.com/…xtension.php#…

Compiler::loadDefinitions($builder, [
	$serviceName = $this->prefix('handler.' . $handlerName) => $implementation,
]);

feeded with config.neon: https://github.com/…andlers.neon

monolog:
	handlers:
		- Monolog\Handler\BrowserConsoleHandler()
		- Monolog\Handler\ChromePHPHandler()
- Monolog\Handler\NewRelicHandler()

In Nette 3.0, the above lines return “Nette\DI\Compiler::loadDefinitions() is deprecated, use non-static Compiler::loadDefinitionsFromConfig(array $configList).”

So I changed them to:

$this->compiler->loadDefinitionsFromConfig([
	$serviceName = $this->prefix('handler.' . $handlerName) => $implementation,
]);

But the behaviour changed. While in 2.4 with loadDefinitions, the generated container looked like this:

public function createServiceMonolog__logger(): Kdyby\Monolog\Logger
{
	$service = new Kdyby\Monolog\Logger('app');

In Nette 3.0 with loadDefinitionsFromConfig, the generated container looks like this:

public function createServiceMonolog__logger(): Kdyby\Monolog\Logger
{
	$service = new Kdyby\Monolog\Logger(
		'app',
		[
			$this->getService('monolog.handler.0'),
			$this->getService('monolog.handler.1'),
			$this->getService('monolog.handler.2'),
		]
	);

Sorry for (possibly) a rookie question, but there's some magic going on I do not understand. I understand that this is desired behaviour in most of the use case, but here not – I do not want to DI these services right away, because I need to set a different order of them and push them manually in the Kdyby\Monolog\Logger (see https://github.com/…xtension.php#…)

Can you please help me understand, what's going on in Nette 3.0 that wasn't in 2.4?
