Dunno if that's a thing, but likely just an idea left since PvZ:AS was upcoming at that same time and also had some plants that were based off Far Future plant designs with other plants typicaly following PvZ2's roster or extrapolation from PvZ's roster in the style of PvZ2.

Walnut Bomb on the other hand seems to be one of the original plants made for PvZ:AS, and could have been inspired enough to be considered for implementation. But I guess that idea just didn't come to fruition.
