iPhones substituted telephoto camera for ultra-wide as a default option at the exact time the "Pro" line emerged. That's not a coincidence. Apple now treats telephoto as a "Pro" feature, e.g if you want to zoom in - pay up. And many people do. On the other hand, it's hard to imagine upselling anyone on the ultrawide camera.
As for Androids, even on lower midrange devices, starting from about $300 (save for Pixels that rely on Super Res Zoom to do the job) it's pretty much the standard now to have at least 3 cameras, one of which is always a telephoto.
