Yeah, the srcset for every device type on every single image seems excessive. I was hoping we could take advantage of file naming conventions and define a way for user agents to request 'filename' + 'variant key' + 'filename extension' instead of the 'filename.extension' file in the src attribute when it wants non-1x images, where 'variant key' is something like "_2x" added to the filename for 2x images. Then you could just flag img tags as having 2x available boolean. I don't think whatwg likes the idea of file names as metadata, though.
