I think there is a big difference between hiking through the dark on an established trail vs doing actual land navigation in the dark.
When we do long day mountain ascents in the fall and early spring, it is not uncommon to set out in the early dark am on an established trail. However we are typically equipped with the proper lighting gear which includes headlamps and handheld flashlights when needed.
On the other hand, land navigation at night and not on any trail is not something I do as there are far too many chances of getting injured or worse.
