Here is a start add subclasses of CWE-74, specifically CWE-79 and CWE-94. CWE-79 is one of the most common vulnerabilities on the planet, including code written in Python, so saying nothing about it would be a mistake.
This is complicated because the only proper solutions to CWE-79 are external modules, which are out of scope. However, I think it's reasonable to make it clear that you cannot solve this at scale with only the built-in modules, so you must think beyond it.
I didn't try to fill in the examples, because I wanted to see if this was a reasonable direction first.
