You can't pull it off until you've got a fair bit of research completed (barring a lucky break with rlyeh, but that usually takes a while too since you need a combination of a commander, insanity, and luck with the order they perform, plus the insanity part means that they're somewhat less than 100% functional). Having an extra mobile temple/smiter/divine blesser on turn 40 is cool, but hardly game-breaking, so I think it's here to stay, even if it wasn't intentional. (And from what I hear, Rlyeh's bonus prophets were intentional.)
