A long time ago, when I was a student, a very wise professor offered me his observed opinion that there are two types of people in the world: Newtonians, and Edisonians. I can't remember, sadly, how he described each group, but he did not speak disparagingly of either and made sure I understood him to mean the world definitely needs both.
In my several years of teaching, I definitely saw two types (and a third which I simplistically assumed could be classified when more information became available). I came to view them as a group that wants to understand above all and a group that wants to proceed above all. In my case, I feel time running out and I need (need) to get my stuff done: at any given moment, the thing I need to get done, typically, is not even even (rarely) the goal, from which I seem always to be distracted by obstacles. My "approach" is a gamble--maybe I'll find an answer quickly, or maybe my time would have been better spent reading. Yes, I "could" have read your specific documentation, but also, I could have read document after document after document (in fact, did) without learning from words on paper what, precisely, was going to be the effect on the screen. In another sense, I "can't" read any more documentation when the pressure to see something becomes too much.
I meant that as a response to your suggestion that I could have read the documentation.
However, it might also explain our two views of the problem. You conclude it can't be done because there is no middle, but given a crayon, I can draw and make a case for a number of middles. When you read "path", you immediately think of nodes on Bezier curves. When I read it, unschooled, I picture connected pixels. If the problem cannot be addressed well in a Bezier-curves representation, perhaps--I ask myself--another representation might be tried, even an lowly ignorant one, like my stripping out the curvature to see the results. With no experience, I'd never be able to "picture" the result as a Newtonian likely would.
I'll say that I would be thrilled with a "middle" which was the result of shrinking the selection, in a novel way which maintains continuity of the contour, to a 1-pixel wide figure.
Edisonians believe in the Principle that "Even a blind pig finds an acorn once in a while." :^) (In fact, every meeting opens with it.)
With heart-felt thanks for your, scripters', work, a sine qua non
