I have Javascript disabled by default, and I notice a lot of websites (especially newspapers) initially have a blurry <img/>, and later replace it with the sharp image using JS. So there is clearly still a need for this feature, even if web developers don't know about it.

The HTML IMG tag also has a "lowsrc" attribute, that is sadly deprecated now.

There's also a proposal for a loading="lazyload" attribute value to allow images to load when scrolled into view https://css-tricks.com/a-native-lazy-load-for-the-web-platfo... https://caniuse.com/loading-lazy-attr

A bit late of a reply, but <picture> allows specifying multiple sizes of images. Which one will be downloaded depends on the criteria the developer set (generally based on the page or rendered image dimensions).

That might have more to do with the variety of screen resolutions than progressive loading per se
