I have no idea what you're referring to. Nothing changed, because it didn't actually work in the GTK2 days either. Actually it was worse then. Themes would break apps constantly. I remember always having to edit gtkrc when something broke, and sometimes that wouldn't even work or the app would just crash entirely. It was even more "fun" if a theme crashed the window manager or the panel and then you had to switch out to a VT to fix it.
