Yeah, I just don't see why Ryokugyu would need awakening for that? Kidd's ability is way more specific, plus, it kinda is the same awakening as Doflamingo and Katakuri (logia-like) used, as he is assigning magnetism to the surroundings. Fundamentally changing the surrounding objects properties. It's not the same at all as Ryokugyu just making plants grow around him. Just like Robin can grow limbs on objects and Fujitora creating gravitaitonal fields around a large area.
People tend to immediately assign any new shit to awakening. "It must be awakening". No, it doesn't have to be awakening.
