Crazy thought: detect viewport size on first load and serve pre-rendered PNGs to skip the rendering on client part. Someone probably already developed that.

  Opera did something like this, but instead of PNGs they gave custom markup that is precomputed so that the flip phones don't have to do layout. Or something like that. Opera mobile had server farms rendering content and re-compressing large images.

  viewport size can only be detected when the page is loaded... Afterwards, the images are loaded. It feels slow ;)

  With this method the content wouldn't be accessible to user agents that are coupled to helpers for persons with disabilities.

  That is essentially what Opera Mini does/did: requests went through Opera's render farm which would request page and render them (with adaptations) to a packed binary format and send that back to the device. There was also rudimentary JS support in the rendering farm, the device essentially got an image with an interaction map, and interactions would be sent to the server for processing. Not very configurable though, can't really e.g. customise font size, observe the page or pass it through a screen reader.

    Not to mention the enormous privacy trade-off of having Opera monitor and screenshot every webpage you visit.
