Description

Dependency injection works fine so far as long as components in a singleton scope are requested. Protoype components can't be injected as soon as more than one instance is needed or the requesting class / method needs to have control over the constructor arguments (which is very often the case).

Therefore consumer code currently calls $this->componentManager->getComponent('NameOfProtoypeComponent') in order to get a fresh instance.

This can be optimized by moving the instantiation into an (abstract) factory method:

abstract protected function createSomeComponent($argument1, $argument2);

This method should be detected by the component manager and automatically be implemented by creating a proxy class.
