You can do this already using <img> elements (in fact it's even more
effecting for DDOSing a site since it happens as soon as the user goes to
the page, not just when the user clicks a link). In practice it's not a

Redirects almost always involve multiple servers in large scale

You can't really do that, just like today users can always just use the
URI and ignore the redirect, they could do that with href="" ping="". In
practice very few users will change that so it won't be a big deal.
