Most of those Interfaces are not candidates for this - they are JCA  
abstractions for different provider implementations or multiple  
inheritance style implementations.

Callback might be the only candidate, but then it is unlikely used often.  
The PriveledgedAction is the only one where it is often used and could  
need some syntactic sugar.

Will the marker affect compilation and normal runtime or is it strictly a  
marker accpeting the interface in the functional context?
