Two possible ideas, and both would slow the rendering down. Camera focal 
blur and/or refractive dispersion. However, neither would be direct a remedy 
for softening reflections.

I'm not certain of what you might be talking about exactly anyhow. Is it 
only the reflectiveness? Or is there something else about it? I tried 
rendering a small section at a large enough size to see the glass columns 
but I'm still not completely sure if it's only reflection causing the sharp 
and dashed lines I'm seeing. Oh, also might be possible to lower 
max_trace_level without causing blackout areas, since I tried 15 instead of 
50 and it looked fairly okay.

As you might already know, the superellipsoid primitive in a CSG difference 
can be slow to render, so I hope you're ready for slower rendering if you 
take me up on my suggestions.  ;)

Have you considered using MegaPOV? It can blur reflections (or at least did 
in some version). And there's also the regular POV version method of 
blending textures, just search for "blurred reflection" and you should find 
plenty of past discussion about it.
