Even if Yin and Yang release are chakra forms they are still not their own element. In fact manipulation of Yin and Yang is stated as the basis of ordinary, non-elemental jutsu. Nara Clan Jutsu is not elemental, neither is Akimichi jutsu, yet they're considered to be aligned with the concepts of Yin and Yang. You want an example of Yin-Yang Release? Look no further than Naruto's Shadow Clone Jutsu. It's a Jutsu that both "Creates form from nothing" (Yin), and "Breathes life into form" (Yang). you can't argue that Yin and Yang are their own elements. They are the basis of all jutsu, and thus all jutsu already incorporates them.
