Indeed. I think there's a confusion around this in general, and  
"responsive images" mean different things to different people.

While the solution that Responsive Images group leans towards is  
appropriate for solving layout problems, the description of group's goals  
sounds more like solving optimisation/dpi problems. I think these are  
orthogonal issues and both of them may be worth solving.


I've tried to sort problems/use-cases here:
