No one is arguing that POV-Ray should tesselate every object by default.
In fact I know I would never suggest such a thing. But there are certain
features that could be added if POV-Ray could be set to tesselate objects.

Some features that would benefit from this would be -

1. The ability to export .pov objects and scenes to other 3D file formats

2. Surface subdivision - currently only possible with meshes and only
   can be done through use of memory and process intensive operations.

3. Displacement mapping - more accurate surface representations than are
   currently possible with surface normal alone.

And this is just a sampling of the things you can do with tesselated
POV-Ray primitaves.
