I have a ComponentsCache which holds Component instances (currently just a flat list of Any)
I use hierarchies of components, i.e. subcomponents.

When I delete component X from the cache, I want to remove it's children automatically as well.
Therefore I need a parent-child relationship between the components.

I could handle all this myself, i.e. have some sort of CacheNode(component, parentCacheNode) etc.

However, I do know child components do have a parent component reference.
Is this accessible from outside somehow? (So I avoid having a multiple sources of truth)
