I would reverse this.
Stream crossings, descending 7 miles on gravel in a thunderstorm, puddles turning to ice, washing with a hose... When conditions deteriorate I'll take Di2 every time.
Save the mechanical for a nice sunny day when there is a 10% chance of maybe getting some pollen on your bike.
