Note that the point I made above was about whether a spec change is something that would actually give authors the ability to control buffering. I wasn't making a point about making changes to a browser.

What this group is is irrelevant to the question of whether authors would actually be able to make browsers download less data by specifying autobuffer="off" given software that's already deployed and out there.
