We're just going to have to agree to disagree Dieter.

Suppose I want to use a web service and use an OA handler to enable CHAIN etc. to retrieve data via conventional RPG opcodes. I don't need to write a handler to deal with everything ... just the operations I am going to use. As long as I protect the user by having the handler error out any attempts at usage that is not supported by the handler then I don't see the problem.

You appear to be looking at OA simply from the perspective of enabling database modernization. I also look at it from that perspective but in addition as a vehicle for enabling the use of conventional RPG operations by folks who don't know (or indeed need to know) all the nuances of using web services or whatever.

I agree to disagree!

I would recommend to provide simply a callable proceure. Why should someone use chain and get's a Not_Implemented error, if (s)he tries a setll and read?
