Extend symfony services with app scripts
It would really increase the possibilty for app developers if every symonfy service can be extended with an App script.
In detail every public funtion of a symfony service should be extendable by App scripts before and after.
This would make much more features possible to implement with Apps comparing now.
We are not planning to expose every Symfony service with App Scripts, because we want to improve stability and maintainability for extension manufacturers, especially across major versions.
We understand that the usage of app scripts is more limiting than simply overriding or decorating existing PHP services. In order to accommodate for the extension points that you need, we ask you to provide us with the specific scenarios (e.g. altering tax calculation, adding data to order line items) so we can build the most stable and expressive API for that.
