What sort of answer are you looking for? There are many ways that
question could be intended.

If you're asking about what could be keeping a particular tree
implementation out of the standard library: that depends on what
particular implementations you have in mind. Are there any which exist
that you think belong in the standard library?

If you're asking about some policy that prevents any such inclusion, I'm
not aware of such a policy.

If you're asking because you think all data structures magically appear
in the standard library by wishing it so, I think you over-estimate the
powers of the standard library maintainers.

If you're asking something else, you'll need to be more explicit.
