Ohh, Let me answer this question.

Im using symfony mostly. In one of my projects, Image Manipulation was needed. So i wanted to create something for this.

Then I said, ok, first create a wrapper for this, maybe some others may need to use it. So i created the photon wrapper.

Back to our case, I need a bundle to use it in symfony. Cause Im also using some other components and packages (a lot).

For example In this case, I will use monolog with this service to log non-accesseble images. So, I need symfony's dependency injection. Creating a service and overriding it would be solution for me.

Maybe some other developers (for symfony) need this bundle. So that, I also put this.

Conclusion,
This is a Symfony Bundle. For only symfony framework. Some can implement it for Laravel or any other framework. Wrapper is standalone package.

I hope I am clear now.

Back to my first comment I said,I understand that, we shouldnt create packages for Symfony, Laravel or any other frameworks. And your reply (I cannot see what you have done.) supports this. Am I correct?
