There is no need to duplicate the method/signal/property arrays that were registered for objects. The registration was using static arrays on methods/signals/properties in all places and we can as well use those throughout without having to allocate memory and copy all the entries for every object. This reduces number of allocations and amount of unnecessary code quite a bit.
