If you read the article also have a look at the project this comes from. It's hard for me to place exactly where this lies between X and Wayland and regular WMs, but is is a pretty bold "I will do this all different" (or at least different than what the mainstream is going with) where the project is really creating something one can actually launch. Which probably makes OPs opinion on questions such as this worthwhile to consider.
