That's good news ! Is it configurable in the interface for each layer independantly ? It should probably be, as according to the style applied to the geometries, the simplification could be something we want for some layers and not for others. A checkbox in the layer properties dialog could be interesting. Then we would have to decide if we want it activated by default or not for dataproviders supporting it. We could have a global option for that default too.
