I suppose I'm coming from the photographer's end of things, I'm not worried about server space, 'someone' just gets some more for me when I need it, and as for speed of download and rendering isn't that taken care of by Moore's law? ;-)
I would caution against only putting metadata in your largest image, users download all sizes.
I have known images attributed to the wrong collection on Wikipedia, now if metadata use became more widespread...

One reason social media sites, as well as many automated tools designed for web, such as the image resizing libraries found in CMSes and so on, strip out IPTC / EXIF / XMP metadata is to keep file sizes as small as possible. You might not think this is a big deal, but in some scenarios, especially where you have lots of images on the page, it can add up. And the user experience of faster loading sites is always going to trump hidden metadata serving no obvious user benefit.
(On your own sites though, keeping the metadata in the biggest versions of the images might still be a reasonable idea)
