I'm not sure about that. Other than doing an oil flush every now and again they're pretty much fit and forget.
That's my experience too.

But, cable disc brakes can use less expensive cables\levers and you can more easily change a cable. Problem is that you need to constantly adjust the cable so that the pads work.
I wouldn't like a hydraulic disc system to go wrong on a long tour, they are more difficult to fix out in the wild.
