There was also a time when people made an argument that the additional
HTTP traffic for "a single advertising banner" etc were not that major.
Now there are lots of sites you can visit that have tons of advertising
on them.

Perhaps I'm cynical, but if Chrome changes the game and the perception
becomes that speculative preresolution is a good thing, then we're
looking at scenarios in the future where client software will be
aggressively doing this.  I don't really care what Chrome is doing
today.  I can see this being a bad thing in the future.

It'll be great fun when Interweb Exploder decides to speculatively
resolve every domain name in your browser history, on the theory that
since you've gone there before, you might go there again.  Hey, look,
I just figured out a great way to speed up the web...  I'm off to the
USPTO...
