About config table in ovm_root

Hi all,
As we know, the ovm_top is the topmost node of the ovm component hierarchy, when we use get_config*, the searching order is " global config table → config table of ovm_top
→ config table of sub node……“.
It seems that the config table of ovm_top is redundant since it will not be used at all, the global config table can be replaced with the config table of ovm_top, is it?
