I am always speaking from the point of view of automatic memory

Lots of pointers to the tree root node. And you also don't want to wait
with collection if you hold onto hardware resources (forcing perhaps
lower resolution graphics if you are low on GPU resources).
If you mean you need to be sure that all references are gone from the
graph, before doing a dispose() invocation, then yeah you need some form
of RC, even with a GC.
However that doesn't mean that the developer/API client needs to care
about it.
It is a matter of how the graph node construction is exposed to the
clients. With proper a proper ADT that can be hidden from the API client.
Automatic resource management requires another type of thinking anyway.
