         The ARMI Framework contains a mechanism to warn users if they ask for the density of a
-        material attached to a component, e.g., ``comp.material.density()``. The problem is the
-        component is the source of truth for volume and composition. It stores dimensions, which can
-        be thermally expanded according to the material and number densities, which may be updated
-        during operation. Much of the framework operates on ``Component.density`` and other
-        ``Component`` methods for mass accounting. However, ``comp.material.density`` does not know
-        about the new composition or volumes and can diverge from ``component.density``.
-
-        Additionally, the framework does not do any thermal expansion on fluids. So the above calls to
-        ``component.material.density`` are warranted if the material is a fluid.
