See also comment here:
Uses spherical development of ellipsoidal coordinates. Relative to an
ellipsoidal development errors of up to 800 metres in position and 0.7
percent in scale may arise. It is not a recognised geodetic system:
see WGS 84 / World Mercator (CRS code 3395).

The error is significant for many GIS applications.
