And actually, by sheer coincidence, I happened to stumble across a PostCSS plugin called "Short", which used this syntax. 

https://github.com/jonathantneal/postcss-short/blob/master/README.md

It also includes using '*' in shorthands to mean "don't change the value that would normally be in this position", which I find pretty intriguing and would be useful for shorthands in general (we could use some other token if that one is problematic).
