The GEOCGS will likely cause a lot of confusion. They need three 
coordinates (X/Y/Z), while most GIS software is still in 2D-mode 
(lat/lon or X/Y). As a consequence, inverse projection (or 
on-the-fly-reprojection) is not possible if the third coordinate is 
lost. See 
for an example.

BTW, any chance to get my http://trac.osgeo.org/proj/ticket/235 included?
It is just about datum shift of the Czech Republic bound to East German 
Pulkovo projections, which leads to unwanted datum shifts.
