That’s irrelevant. Most of the Web users are using mobiles, so if you decide to set a website up, the very basic thing is to ensure it’s readable on mobile. And since plain HTML is already readable on any device by default, it would be quite strange to voluntarily make it unusable on these devices.
The mobile crowd may not be your desired or intended audience though. It's fine to publish a website in Icelandic even if more people could read it in English.
