And you thought it would never happen

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Same applies with hydraulic disc brakes. Your only failsafe is in having 2 independent brakes.
I think the important thing here is that the two brakes on a conventional system truly are independent. Hopefully any electronic system (without mechanical backup anyway) will be truly redundant. This would mean two separate batteries, unlike Di2 shifting.

Hopefully it can be configured to brake when pedaling backwards.
