What was the point of changing the rendering of skysphere?

What are you talking about? What was
changed from what to what? (This isn't meant
as an offense, I really have no clue what you're
trying to say here, to which POV-Ray Version
you're referring for "change" etc).

	I noticed it just the other day. Make a scene with just the skysphere,
no ground plane and look at the results. The "top" half looks almost the
same, just a little different as some things do. The bottom half is
completely different.

There have been no functional changes to the sky_sphere since its introduction
in version 3.0.

Maybe you use a gradient pattern which changed in POVRay3.5 (Docs,
6.7.11.17) for the negative direction.
If you want the old gradient, you may use a function {mod(abs(z),1)} or
something like this...
And the top half may uses some kind of noise (bozo,granite,etc) whose looks
changed due to the new noise_generator...
