There are cases when it is really needed (or you would have to access the address and data bus by hand). In my case I'm using a Xilinx PLB soft-core and if certain options in the configuration header aren't set (which aren't set by default) the soft-core is basically disabled. Cases like this look like valid cases in which early config should be used.
