As the author himself said, just React was downloaded half a billion times; that is a lot of saved bandwidth on both sides, but especially so for the server. Maybe it would make sense to only apply this improvement in images that are a) either very big or b) get downloaded at least million times each year or so. That would cover most of the savings while leaving most packages and developers out of it.
