No, it's grasping at straws. That's not logic.
To go from a datamined file about a "Voidelf" to the position of saying "High Elves will be a playable race for the Alliance" is, as you said, a huge [and false] leap. Especially one for an OP going around screaming like he's 9 years old and telling people they're "making something out of nothing".
