I can see that. But what types of intractableness have you run across?
The obvious examples are non-linear, non-monotonic dimensions that are
really a combination or function of multiple dimensions already.

For every visual depicting a good transform function, there are an unbounded number of obvious but defective transform functions that will produce an identical visual. Don't underestimate the subtlety of the theory; it stumped academics for a couple decades.
What do you call this type of theory / topic? What are the foundational
papers here?

How much more scalable?
