I don't develop offline often these days, but I do recall a recent time where my power went out for a few hours. Since I was using git on my laptop, I just shrugged and kept working. Using git allowed me to continue working in a flow state that would have normally been interrupted by a dropped connection. Of course, if your project doesn't run locally, that point is moot. For others, in areas with more power/connection interruptions, the time savef would add up.
