Well, so would I. I went back to metacity when I realized I had turned the duration of all beryl effects to 0 second because I had a general feeling of slowness otherwise (especially the desktop cube, fading menus etc). But I think this kind of animation is not aimed at speed-clicking-keyboard-shortcut-nervous kind of people like me :), but rather at people who have little experience or knowledge of computing, and expect the interface to be obvious and self-explanatory. I guess there could be a centralized place for semi-advance people (ie : those who don't want to touch gconf) like the new appearance capplet where you could disable animations.
Before I accidentally used a gmail shortcut, I wanted to say that I was trying to express Alan's idea. Is it something like this ? If not, could you correct me ? :

From what I understand, you would like the entire choices to be higlighted rather than just the radio buttons ?
