I think the docs [0] are a good way of evaluating the article's high horse claims, and as far as I looked around, I'm not seeing anything new nor interesting. The author seems to be more or less just reimplementing Vue from scratch. This makes the whole condescending tone funny, if not sad.
There seems to be two ways to interpret Nue:
1) This is amazing, thank you for the important contribution to the web!! 2) This is high horse / funny / sad...
I find this interesting. People can make up their mind from the link you posted.
I only know Vue as "like Svelte, but without compiler goodies".
So to me a "Vue but built 100% on web standards" at least has a unique selling point.
