Chrome aggressively pushes new "features" with pretty much zero-regard for user privacy. Prefetch is a particularly good example in that it has no real benefit to the end user, while also providing yet another tool for tracking. Outside of this there are a bunch of features that are implemented in webkit, that are not enabled in the system frameworks due to them having significant cost to end users.
