You bring up interesting examples. The only one I know anything about is shape note singing. I guess your point is that shape note singing can be taught much more easily to beginners, and get them to a point of being able to enjoy making music (usually with others) more quickly?

If so, point taken!

And I guess that those shape note singers who feel the pull to perform/compose more complex music can then simply learn traditional notation. Self-selection, with a satisfying "intro" notation for those who are happy at that level.

Following that path, I'm still not sure that the original article here provides anything useful. It's simply an alternative to traditional notation. It doesn't seem easier to learn to me. I could be wrong, but I doubt that I'm an order of magnitude wrong. In fact, if this new notation were proposed as an alternative to shape note singers, it would seem to undo the very reason for shape note singing in the first place: easy entry point to music making.
