That's one possibility. An advantage would be that it
would be easier to add methods in the future that apply
to UsualTreeNodes but not FinalTreeNodes.
Another possibility would be to just rename the classes.
Instead of FinalTreeN

Do I understand correctly, than C3 applies to particular methods, and thus
it does not fail, if it works for every defined method, even if it can fail
after addition of a new method?
Also, at which point it fails: at definition of a class or at calling a
particular "wrong" method?

I am developing software which shows hierarchical information (tree),
including issues and comments from BitBucket (comments are sub-nodes of
issues, thus it forms a tree).
There are two kinds of objects in the hierarchy: a. with a (possibly long)
paginated list of childs; b. with a short list
