POV-Ray never supported the "^" in any final version, just a few beta
versions of POV-Ray 3.5 had support for that operator.  So this is in
absolutely no way a removed feature.

Yes, you just apply yourself the operations the old unofficial isosurface
function implementation of "^" did implicitly.

Because it did not conform to the general rules of mathematics.
