The reality is that in disabling WebGL, you have an incredibly unusual configuration and the author didn’t test for it. Stop making this a philosophical argument. Why does the documentation need WebGL? It doesn’t, but the web has moved beyond just addressing “needs”. Why do you need to be on HN? You don’t. Yet here you are. I’m not arguing that the juice is worth the squeeze here, but your argument has a false premise that you’re exploiting to make the situation sound more absurd than it is.
