I mean it's not like it's a different group of people now. Out of the development team for the original game, only one person definitely doesn't work at Nintendo anymore (Hiroshi Yamauchi, Nintendo CEO that retired in 2002 and died in 2013), and possibly I. Marui (who doesn't have much info online in general). And Eiji Aonuma has been producer since Ocarina of Time in 1998.

So, while it's questionable how much involvement some of the team may have had with this timeline, it's entirely feasible they could have gotten input from the same people that wrote the games from the very beginning.
