To use separate refinement patterns.  For a simple example, the solute
layers you might want to adaptively resolve in a concentration
variable for a transport problem won't necessarily have anything to do
with the boundary layers and/or corner singularities in the
velocity/pressure variables.  It's not a bad idea, it's just very hard
to do in such a way that the computational overhead of maintaining and
integrating on separate meshes doesn't overwhelm the computational
benefit of getting the same solution quality with fewer redundant
degrees of freedom.
