Mesh control entities can smooth the mesh locally when the entities are removed, so they generally produce better-quality meshes locally, compared to leaving the entities in the model even if there is no boundary layer mesh. That is, the mesh can be perfectly reconstructed when the absolute position of exactly one coordinate is set, but the reconstruction problem turns into an overconstrained linear system as soon as multiple constraints are added. ICEM CFD has significant amount of options and settings to get a quality mesh at the walls and coarsening in the 'farfield' regions.
