Well, in fact it is rather the x-z plane (but that does not change a lot

Well, your code is bogus for infinite plane: just step the camera back a
little step (-50 instead of -5) and you will see the mirrorring of
gradient !

Agreed, that's why I usually refute evolution asking for #for and other
syntaxic
sugar.
Nevertheless, a point for me: The rendering of with your code take (with
AA=0.3)
235 s while mine only 161 s (sample per pixel was 2.49 for your, 2.64
for mine,
with simple pigments rgb<1,0,0>,rgb<1,1,0>, rgb<0,1,1> and rgb<0,0,1>)
The memory consumption was also less with my code, about 1.5k over 92k
The image were not identical because of the gradient mirroring and the
ordering of
pigments (which may explain the different sample/pixels).
Either way you take it, as a 45% more time or 31% quicker, I do not
think the difference
is small.
Taking your argument to extrem, you should remove the sphere and box
objects, as they
are specialisation of the superellipsoid, and it also seems that the
cone can be removed
as also a specialisation of some quadric or quartic (or was it a more
complex polynomial
equation ...).
My motto is: KISS (Keep It Simple...)
