Agreed in priciple, as a logical design. But when transposing the logical design into a physical one, it might be sensible to normalise further in some selected areas for application flexibility, and/or to denormalise (carefully) in others for performance. IMHO though, each such change should be considered carefully, and a justification documented.
Just my 2c.
