The vibe I got from reading the "why" section was "yeah we had some fun making this, and yeah we think this syntax is a bit better, but isn't it ridiculous our boss thought this was a good idea!" Like a wink at anybody who think this isn't needed.
So to the extent I think its a joke, I think its intentionally a joke --- and whoever made it I respect their comedic talents.
I totally missed that the boss wrote that page. Maybe I wasn't perceptive enough but it came off to me like employees taking a crack at their boss. Not in Dilbert-style disrespect more as everyone turning an eye-rolling issue into a fun project. It was funny.
I just didn't think it was you, though. Maybe sign it "The Boss" or something similar at the end to make sure the rest of us get the full joke.
