I use it all the time, both in ad hoc queries and in data prep for models. Most commonly just to look into a future window from the current event (i.e. did this pass in a game of soccer lead to a shot etc). It's quite rare that I'll specifically care about X rows preceding or following but it does happen that you care about a shorter period than the entire window. Entirely possible people are using graph databases for that sort of thing, but the window syntax is nice.
