The ManagedComponent view is an admin client view of the deployment metadata, including any override values applied previously. This view would show the value of properties that are specified at an admin domain view, but if I change such a property I have overriden it at a component level. It is a post admin edit view. If we are to allow editing of a local server domain.xml, changes to a ManagedComponent view would have to propagate to the domain.xml. Changes to properties that are dervied from some higher level admin domain would not be propagated because you would not be specifying the domain level value. The admin domain would have a separate component for that.
