Thanks, comparing positional encodings, MoEs, kv-caches etc are all good topics that I have in mind for either supplementary material and/or a follow-up book. The reason why it probably won't land in this current book is the length and time line. It's already going to be a big book as it is (400-500 pages). And I also want to be a bit mindful of the planned release date. However, these are indeed good suggestions.
