At the very start of the movie, Jyn is held at an Imperial labor camp on the planet Wobani. Seems normal enough, right?
Well, the franchise has a history of including in-plain-sight nods to Obi-Wan, and Rogue One is no different, because of course, Wobani is an anagram of Obi-Wan.
Considering the alternative was probably including a crude CGI recreation of Alec Guinness for the fanboys to get their fill, a written reference was probably the best choice.
