I'm not sure if you understand it correctly.  POV-Ray does support vector
functions in form of transform, spline and pigment functions.  Just for
defining a vector functions through formulas you need to use a pigment
function with an average pigment.  This can be simplified with macros of
course.

So by using vector functions in your patch syntax you don't loose
anything, you just gain additional options.
