Having a little experience of exploding bolts, it's actually fairly straightforward to design a system which, in both senses, is tolerant of both a single undemanded bolt actuation, and similarly a single bolt that fails to blow when required - if you want to consider double/triple failures that can be done as well, it's just a bit more complex.
A bigger problem might well be finding any existing ground crew able to deal with explosive devices on civil aircraft. Or airports comfortable having them sat on the pan - particularly given the huge amount of EMC affecting radiation swashing most airports, which can be bad news in conjunction with electrically operated explosives.
