I agree with Romain that we cannot change the semantics of existing 

Furthermore, I think that instead of these tricky context propagations 
we should promote async event-driven architecture where as much state as 
needed is carried within the message / event payload itself instead of 
clients relying on state from context, threadlocal, etc.
