This is not intending to minimize in the slightest the amazing work that Jeremy does - I am a huge fan.
But Fast.ai has TWO co-founders, and somehow, Rachel doesn't seem to get any credit in these discussions (not the book specifically, I'm talking about the overall enterprise). Not quite sure why; A lot of the content on the website is written by her, and it's clear she adds a lot of value to the endeavor as a whole.
Thank you for mentioning Rachel! :) She is working as the Founding Director of the Center for Applied Data Ethics nowadays, which is a very full-time job. So she hasn't been involved much in fastai v2 or the book (other than chapter 3, of which she's a co-author).
She created and taught the NLP and Computational Linear Algebra courses, and has written most of the material on the fast.ai blog, and of course (as noted) co-founded fast.ai. Overall, I'd agree that she doesn't get as much credit as she deserves. That's perhaps partly due to her increasing focus on ethics issues, which aren't generally discussed much on HN (sadly).
I also would say that Sylvain Gugger doesn't get as much credit as he should -- he has been an equal partner with me in creating the book and fastai library.
(I discussed this response with Rachel prior to posting it.)
