The link you provided links to a series of pages about (mostly) Python, some SQL and a touch of scheme. Interestingly, it doesn't talk about using scheme as a programming language as much as using python to create interpreters which interpret a small subset of scheme.

I think most people would look at that corpus and say "that's a Python text."

It’s the current version of the textbook for the current version of the submitted course (CS61A). I don’t understand the point you are trying to make. It was an appropriate addition to the discussion.
