I mean the system of passing functions rather than vectors or color
values. What kind of node does this make possible, which is not possible
without passing functions?

My point is, that I can't really think of one with practical use.
Simpler things like blurring or sharpening can be done with texture
derivatives, more advanced things seem to be inefficient or difficult to
the point of not being useful in practice.
