What if it had a comment section where people could discuss these issues, like the PHP docs? What if it had a wiki, where people could collaborate on fixing them, like ArchWiki?
I've pointed out errors a couple of times and they were corrected pretty quickly.
The article gets to the right conclusion, develop mobile first. I'd put it more generally as develop for the most constrained devices you intend to support. If they had done so, it would have saved a lot of time (some of their expectations about APIs still would not have been met).
