A large portion of Chapter 1 (https://book.mixu.net/css/1-positioning.html#float-positioning-scheme https://book.mixu.net/css/1-positioning.html#float-positioni...) is dedicated to the intricacies of floats and their special flow, explaining how their behavior can be carefully reused and adapted for alternative purposes. I'd say that's as pedantic as anything can be, especially given the lack of flexbox/grid layout when it was written.
