By that same logic, Pakura's Scorch Release can't be wind and fire, and lightning should be dropped from Explosion Release. None of them ever displayed these natures, nor were ever mentioned to have them. Shinki has displayed as much wind and earth use as Rasa, the difference being we had explicit confirmation of what Rasa can and can't use, while that's not the case for Shinki, no graphic spread showing shaded kanji for him.
