I know Game Freak as my own hand's palm, and I found VERY weird of them to program the last mythical's special item (Marshadium Z) in the first Gen's games. Right, they already did it with the plates on DP and Genesect's Drives on BW but the plates can also be used by any Pokémon and the Drives are unobtainable without a fateful encounter Genesect, but the Diancite wasn't programmed on XY same with the Prison Bottle.
I think I did the best decision by buying the game early only for the Snorlium Z (even when is the worst game so far)

Yeah, story, music and characters are better than XY, but SM removed so many things that they have the least features or the most annoyings (Why did they had to remove the Battle Institute? Why is so fucking difficult to get an in game Gengar? Why does SM doesn't have a National Pokédex?)
