Possibly because they aren't needed? Under what circumstances would you use
a tree instead of a list or a dict or combination of both?

That's not a rhetorical question. I am genuinely curious, what task do you
have that you think must be solved by a tree?

Also, what sort of tree? Binary tree? Binary search tree? Red/black tree?
AVL tree? Splay tree? B-tree? T-tree? Scapegoat tree? General n-ary tree?
Every possible type of tree yet invented?
