There are a lot of kinds of Zelda games: the 2D open world that the NES ones were at the time, the more structured 2D worlds from ALTTP, ALBW and the GameBoy and GBA games, the first 3D limitd open world of the 64 twins, the full 3D open world like WindWaker, more structured ones like TP and SS... They don't get attached to one style, at least in that regard. And having into account how expensive and difficult to make an open world Zelda must be, they won't want that.
