Actually it was relevant. The statement that Water Wind and Earth elements already have a spike version can lead to the conclusion that it would be out of cannon for SE to add 3 new spike spells.
And I don't believe your example of Phalanx is relevant. The protect and shell lines of spells are also Light Element. I don't think it's unrealistic to concider Phalanx, Shell and Protect as separate spells outside these 8 elemental spikes. You could base this purely on the animations of the spells.
