Unlikely performance. Google search results page is relatively heavy, with Google+/etc. And this one, is a simple change of a few lines of code. Yes, sure, it is a default behavior and I also don't assume malice (evil = lazy / stupid / don't care about users, not malice). I'm just surprised about the oversight, that they apparently don't care about having slightly better click types data and also making the user experience slightly better.

(And BTW, this is again compliment to Google, as I'm surprised. Not assuming that by default, as any other big co they've just filled with bozos.)
