As a real-world example, Launchpad currently stretches the width of 
static images to produce simple bar charts of how much particular 
software packages have been localized.
<https://translations.launchpad.net/ubuntu>

We have to specify both width= and height= for the images, because 
specifying width= alone causes w3m to stretch the images vertically to 
maintain their aspect ratio. Meanwhile, elsewhere we're using <canvas>, 
so we should really be declaring our pages to be HTML 5 site-wide.

The sentence Henri quoted would require us to choose between 
server-side generation of every chart image, incompatibility with w3m, 
or non-conformance with any HTML specification. I know w3m isn't 
exactly a major browser, but I don't see any good reason for having to 
make that choice.
