I’d make the case it is the opposite. One off-brand browser can hold up the industry’s migration for years.

The cost model of images is such that you only get the full benefits of a new compression system if it is so widely used you can abandon old formats. That’s because the cost of images includes storage, transfer, plus handling and processing costs. If you have to maintain a large number of different formats, say JPEG, WEBP, AVIF,and JPEG-XL it’s just awful.

I can’t really use a new format until Safari supports it on mobile and mac at the very least. My take up of WEBP was considerably delayed because Apple was slow to get it in Safari on older Intel macs (one of which i have.)
