@dwright: Thank you for your feedback. In my opinion neither RSS nor iCal is really suitable for that and all programming languages support parsing JSON anyway. I don't see that as an issue. EPP is a totally different story. Yes, we could propose an EPP extension, but knowing the process to achieve that, I would advise against it. It would be a rather long process and I think we rather want a quick win instead of dragging out.
