I am not sure what would be the advantage of that... Just to decrease
the amount of duplication among the interfaces?

That is not how we have done this so far--we have always added the
callbacks to all interfaces that need them. I can imagine having a
single function, e.g., createChartInterface(), that would return an
instance of a hypothetic RVNGChartInterface. It might even be
preferable. But it seems weird to do that only for charts. We have lots
of other duplication in the interfaces.
