1) Metacity can do compositing. Why isn't this the default, and why doesn't it anti-alias even if you do turn it on?
Metacity is SLOW. It's slow as f*ck. Maybe that's why it's not enabled by default?
2) Metacity almost exclusively runs together with Compiz. Why doesn't Metacity take advantage of that?
Metacity is a window manager, and so is Compiz. They can't run both at the same time.
Metacity and Compiz are separate window managers. Compiz supports metacity theming that's all.
You cannot do anti-aliasing without composting. Instead you have to do a step effect around the corners to try and make it look rounded. We have to do two versions of the background and panels with Plasma themes(opaque) because there is no alpha when desktop effects is turned off.
Eh?
So where does it get the alpha from then to do the transparent pixels?
Just compare the corners of any window deco on any OS and you'll see the same result, it's a step effect because the bits in between cannot be transparent(which Anti-Aliasing uses to make the corners smooth)

Thom,
You do realise that Metacity and any other window managers, cannot have anti-aliasing without compositing?
If you're running Compiz then sure since that is a composting window manager, metacity isn't by default so it's impossibe to do anti-aliasing since there is no alpha.
