Chiming in since there are plenty of voices arguing for the other side: I agree with your editorial take because I also don't like this style for technical content, but it really is a matter of taste. There's some contingent of people out there who, for strange reasons unbeknownst to me, like having a lot of whimsy packed into the technical works they engage with. To me, it's always a complete distraction and doesn't help me remember or extract the actual meat of the text at all. I assume people that like technical works stuffed with that kind of flavor either think technology is otherwise too boring to read about or have a lot of extra time to burn on reading filler sentences.

But, that aside, I think this is a grand slam. Kudos to the author.
