The 1st is inaccurate; the time skip mentioned in BotW was not from OoT, as BotW itself mentions the Guardians existed prior to the time skip. This game is part of the Downfall timeline and taking place centuries after OoT (it's the same Link as ALttP and ALBW).
The 2nd point is irrelevant...
Oh, come on... Couldn't you see it as a Guardian laser? It would make a nice cameo in a game that, if faithful to the original, is already full of cameos.
