Do we want to add styling for good/bad code blocks to PEPs?

For an epxample, look at pep8.org, a third-party (and outdated) rendering of PEP 8
The main difference between it and the new style proposed for PEPs is the red & green indicators on what to do vs. what not to do.

I've just read the dangerous "naive" SQL code in PEP-0675 and thought it could use a similar "don't copy this" indicator. There surely are many other examples.
Of course everything should be covered in prose for screen readers and color-blind people, but for many people colors could aid understanding.

Would it be useful in docs as well?
