The fun starts when you have an engine failure after your SID deviation point.
Simple matter if the backroom guys are doing their job properly.
Suggest you ask your flight standards folk (or ops engineers if they are in house) if the engine failure case has been examined for the entire SID track. Our procedure always was to make sure that a failure, anywhere along the departure track, was accommodated by the OEI procedure. If your folk don't do so, perhaps you should ask them to come along for a ride on the relevant departures on a regular basis ?
