My only caution: When parked, don't lean the bike in such a way that a shift button is pressed. That's the easiest way to drain a battery prematurely. If you take that precaution, Di2/hydraulic should give you worry free service for a long time.

I wouldn't want to use Di2 for touring in a 3rd world country, but for touring in the US I wouldn't hesitate.
Di2 and Shimano hydraulic brakes are very reliable.
If Tour Divide competitors are using it, it's probably good enough for your touring needs.
