And the exact same thing can be said about “Java” or in this instance “Python” or any other jargon. Why does no one ask for those terms highlighted? All technical documentation is not a Wikipedia article. It’s just not appropriate imo.
I'd posit that the user base of java, python, etc, huge topics in their own right, vastly outnumbers the users of CAN. It should just come down to simple numbers. I'd welcome that linkability too, makes bridging out to new unfamiliar territories go a lot smoother for the uninitiated. Call it improving the discoverability of things.
