Multilayer well in saturated/unsaturated flow model?

Are multilayer wells supposed to work in unsaturated flow model or only in saturated flow model?

Thank you.

The also work in variably saturated flow models, but: Discrete features connecting along the well pipe are switched off above the water table (at p<0) and pumping well nodes (placed at the botttom of the multi-layer well) are also switched off if they are on dry nodes (p<0).
