Component vs. Node
Why does the ConfigurationBuilder uses its own Component class rather than
Node? They looks very similar to me.

Yes, they are very similar. But you will notice that the Node has a reference to its constructed Object, its concrete pluginType, and most importantly, its parent. When a node is constructed its parent node already exists. That is not true with components. They are created from the bottom of the tree to the top in the build method, while Nodes are created from the root node down.
