Is it possible to use those conveniently-placed-if-only-we-could-climb-them tree roots that descend over cliffs, like in Cirdas, Moh/Sih Gates, and Morimar? They currently have never been targetable for me, but does colonization rate make them into targets? Or is there a key item for them? Or are they merely for a future version update?

I'm not referring to Knotted Roots at all. If you don't know what vines/roots I'm talking about, go pioneering, yo.
