the game has no way to tell the player in advance something like "this system is here just for flavor, it's not really the part of the game, ignore it if you wish".
Except exactly this one.
Wich sounds exactly as something that could easily be part of tutorial tips. :P
But even if, the game certainly do have means to tell the player exact oposite ...
I didnt play Zelda, so i dont know what you were referencing ... but personaly i would expect if the game will require me to kill last boss with a weapon that my character will personaly forge, to warn me about it before i go to that boss ... and there is many ways to do that.
