The problem is that filling in the gaps creates a maintenance hazard. As
another example, the kernel does exactly this kind of thing to initialize
the system call table. Using the override in this way is the clearest,
easiest to maintain way of expressing this.
Disabling the warning not only gets rid of the warning, but should also be
seen as a "something special is happening here" flag in the code. With the
warning disabled, there is a hazard of now missing the possible
introduction of an override here, but I think that risk is less than the
risk of failing to fill a gap when changes are made.
I completely support doing this in exactly this way.
