@W0rma Hi, sorry for the late response. Yes, I can still work on it.

I worked on this some time ago, my concern is whether the approach I've copied from JMS is still valid for this or whether there are better ways to accomplish it.

In any case, let me go over your comments.

Thanks

@ixarlie Thank you for updating this PR!

The code LGTM. However, I don't have the possibility to test the changes since I don't use the annotations in my project.

@goetas Any thoughts about the implementation in this PR?

[goetas]

I will look at it mid February, sorry busy times 😞😢

This PR can also move the doctrine/annotation in suggested requirement to enable some project using it to remove the doctrine/annotation dependencies?
