Having grown up with a plethora of cascaded main fuses I absolutely second that! If those fuses are located ahead of the board it also facilitates replacing the entire board because you don't have to get the PoCo to pull the pole fuses.
The extreme are apartment buildings that are set back from the street. One set of fuses (e.g. 160A) at the service entrance at the street (pillar). Then where the service enters the house (100A). Then each apartment got individual fuses (20 or 25A) ahead of the meter. Single family homes leave out the second set of fuses.
