And

> given how important mobile browsing is to every site

I find my own sites get ~5-10% mobile visitors. It's even pretty simple text-based stuff that renders fine on mobile (at least on my own Android phone), so I don't think I'm scaring them off. But I just don't get mobile visitors, either on my academic sites, or on some commercial side projects.

So while I do check how things render on mobile, if only because I occasionally visit my own sites myself, I don't yet consider it an important demographic for my own work. And the proportion of revenue it provides on the commercial sites is even more paltry, typically 2-5% of ad & affiliate revenue, less even than the usage share.
