They only changed when they'd get hurt and poofed, probably while fighting a corrupted Gem or during bad accidents. Since there's no more corrupted Gems there's not much of a reason to travel around and thus there's not many ways to get badly hurt. Besides, we know Pearl and Garnet kept their debut forms for the first twelve years of Steven's life so it's not impossible.
