I'd be happy to be wrong, but this sure feels like another instance of a numbers/formulas/algorithm-oriented person wanting a shortcut to visual style. This site is full of these, in many areas of endeavor. As a musician, I particularly notice posts that do this kind of thing with music ("I've Invented a New Musical Notation That Makes Everything Easier!").

I just get sad for the designers who have to battle this stuff every day. No programmer would take "input" on their code from a nurse (say), but designers face "input" on their decisions and their craft at every turn. I've yet to meet a designer who was longing for a web form to input a bunch of numbers to generate some type sizes.

But I could be wrong. It happens a lot.
