There are two primary reasons for this renaming: 1. It better reflects the actual nature of the proxy object, namely that the form is represented as a tree, and that this object is used for navigating the tree structure (while `FieldState` is used for getting the state at a particular point in the structure). 2. This frees up the name `Field` to be used for the directive that binds a `FieldTree` to a UI control. PR Close #64214
