For millions of people with flickr accounts I suspect imposing a 
requirement to provide alt text for each image would quickly drive them 
to a different service that did not impose such a requirement. Yet the 
_point_ of flickr is the images. You cannot force people to enter 
metadata, much less the kind of high-quality metadata needed to explain 
the meaning of something visually complex like an abstract photograph.

I think there is a fine point here that may have been lost; the alt 
attribute is only to be omitted *if there is no alternative text 
available* i.e. the draft is attempting to distinguish alt="" meaning 
"this is a decorative image" from (no alt) meaning "no alt text has been 
supplied".
