Plotting charts also give an improved SA about your en-route alternates. Given some guys fly 2 or 3 hr diversion times, I suspect the airfield circle will be off MAP on the ND. And, as has been discussed, and ETOPS diversion might need to be to 'nearest suitable' not necessarily the further ETOPS allowed ALTN. Sitting over the middle of nowhere, day or night, without having an idea in which direction & how far your bolt hole is, IMHO is not as professional s it could be.
