And yes a jinchuriki technically only works with Biju, but the practicalities of it are the same. An Edo Tensei also is a host with a soul sealed inside it, just like a jinchuriki is a host with a soul (a biju) sealed inside it.

If being a double jinchuriki (proper) was very bad for a person, we'd be seeing the effects on people like Kaguya or Naruto.
