Hi Pete, others!
I found the issue I was searching for:
One of the discussions in the EG meeting was about whether we like to have 1 AnnotatedType
per physical class or if we allow for multiple of them.
Both ways have pros and cons.
If we just have one AT per Class, I think we don't need the freshly introduced
ProcessSyntheticAnnotatedType neither. Especially the trick with the getSource() sounds
pretty error prone to me.
