It is not only about loosing or gaining information, but also about 
usability. (If it ain't usable, then you can't use the possibly rich(er) 
information ...)

The draft as it stands does not have any advices especially directed 
towards CMS-es and image sites etc.

If we could move to discussing the right advices to give about how 
CMS-es should act, then I think it would be a step forward in the debate 
- and the spec. I would assume that if we actually gave ourselves that 
task, then we would easily be able to agree about at last *few cases 
where* an alt would be better than no alt.

And thenafter, we could see wht to do with the rest.

"Look, no alt, but still valid" can also be a form of badge hunting.
