> What? What about the vast majority of links that appear in-line, in text (think Wikipedia). What about the increased bandwidth usage for pre-loaded pages I don't intend to visit? What about the obvious tracking issues?

These already exist. You can do <link> prefetch now ...

But I THINK they are doing preload now as well so the DOM can be pre-cached.

I mean you could do it on your own site but most people try to make sites FASTER not slower.

I still don't grok the main advantages of Portals though.
