Well, yeah, which puts a bit of a kink in it, since well, theres very little that the element tagged spells do that the class can't already. Fire gets a small out due to the sheer array of fire damage spells and heck, any spell substituted to fire, they get some utilities bound up in those.
The trick is that these spell completion stuff work best for the elementalists at low levels, about 1-4 or so, where not all the iconic class powers are realized yet. Once you get to level 10 or so, theres really nothing much the spell completion toys can give.
