This may be true is cartography.  It's only partly true in geodesy --
some authors make a distinction, e.g.,

   W. A. Heiskanen and H. Moritz, Physical Geodesy,
   (Freeman, San Fransisco, 1967)

use spheroid to refer to an approximately spherical shape.  (This was,
presumably, its original meaning.)
