Why does vtkConnectivityFilter not preserve point or cell data?

Dear all

I noticed that vtkPolyDataConnectivityFilter doesn’t preserve point or cell data. Any particular reason for this behavior?

I see that the connectivity filter may discard points and cells. Because the remaining poly data isn’t altered, it should be possible that array data is preserved for this remaining parts, shouldn’t it?

I’m running vtk 8.1.

Thanks
