That comment in the Mozilla FAQ seems a bit silly. The privacy and bandwidth implications are inherent to the feature, not something you can code away. For example, there's no possible way that you can avoid using bandwidth to download linked pages.

To me, the real argument is in the next section of the FAQ: "The user preference to disable <link> tag prefetching may simply encourage websites to stick with JS/DOM hacks, and that would not be good for users."

I don't think this is a strong argument, however. There are very public browser preferences to disable Javascript, cookies, plugins, etc., but web developers continue to rely on them all the time. If the browsers support link prefetching, then the web developers will use it, because they will assume (correctly) that most people won't change the browser's default settings.
