It would require at least some basics there, or even accessibility properties, but I am still hoping we can avoid what I had to do for TVirtualStringTree in 2007, implementing literally two IAccessible interfaces, one for tree, one for the focused tree item. That all was managed by a singleton class instance, and juggled quite a bit. Pretty unreliable, so I hope we can make it better in TTreeView for the LCL.

And from what it sounds like, it makes sense to wait for your patch so I, or we, can then build on that and make the Windows implementations better.
