Generally, I am always for something that is easiest to understand even
for a very beginner C++ programmer. Every time we have a factory and
similar thing to use directly for the interface or something that we
have to deallocate, it is a potential problem. I would love the
programmer to have the easiest possible interface that is understood
even by an untrained monkey. And a class of purely virtual functions is
really wonderful for this.

We can always have implementations having a common base and forwarding
the different callbacks to the common base. We do it already in
libodfgen anyway, but for the interfaces as such, I would just keep them
independent.
