I was more thinking that it would be the implementor responsibility to deal with the potential race condition. Do you
see any issues with that?

Sure, async context should be able to take anything that can be considered as a valid return type of an http resource
method as a parameter. Also, I assume that the combination of suspended http method and resource annotations and the run
time type of the response should be enough to choose the right marshaller. I was also considering to generify the
AsyncContext, but decided not to do it in the end. We may revisit that if you or anyone else in the EG feels it might
make sense.
