Well, I'll answer you from my experience, maybe I'm wrong.

About your first question, you are totally free to use a encoded BP or BPL and DTL, as you prefer. I usually prefer to use BP by code for custom objects and DTL and BPL when I work with HL7 messages...why? because I'm too lazy to write code foreach transformation of field in an HL7 message.

The Business Service used by the RecordMapper has a property called Synchronous Send:

 

When you check it the Business Service is going to send the record mapped in a sync call to your BP, so it's not going to read a new line of the file until a response is received from the destination.

About the OnRespone, you can check the official documentation: https://docs.intersystems.com/iris20231/csp/docbook/DocBook.UI.Page.cls?...

I usually implement the OnResponse to receive Async responses from Business Operations called by my BP, in your case I think that it's unnecessary, but this is a personal opinion.

I don't think that is possible out of the context of a production, at the end the destination of the routed message is always a business component deployed in a production, the context info and the messages are linked to components of the productions too. 

I think that is easier to learn objectscript than try to adapt the behavior of the business rules.
