Why do you talk about iterators? There is no iteration here.

There is insertion and removal from the tree matching the definition
that a CA is non-functional as long as there is no subordinate object,
and the accounting followed that. I don't see how that is complicated or
unwieldy and it certainly isn't more copmlicated than your logic.
Perhaps the naming wasn't great and one of them should have included a
DEC. The pattern exists for several other counters.
