Bastien Nocera told me that the plan is t reduce automatically and gracefully the most resources consuming effects if needed.

Given that I can use gnome-shell with vnc/spice, I see no reason to not be able to do it with vmware virt system.

I cannot speak for the reasons, because I really don't understand enough to comment. However, when I tried Gnome Shell/mutter in my VMware session under F-17, that was noticeably slower than fallback/metacity. It was also consuming a lot more CPU.

Well it is going to use the CPU to emulate the effects versus the non-existant GPU so your CPU/memory usage will be much higher. I am not sure that the items Bastien was talking about are in F17, F18 or something being worked for F19.

Which brings us to the real point: what is the purpose of using 3D rendering here? Is it to display (more or less) useless animations and endless screen changes (i.e. overview) or is it so that _appropriate_ hardware does the job of rendering? With Gnome 3, it appears to be the former.

To be fair, I just tried with F-18. It seemed faster than F-17 in this scenario, but all Windows were distorted (half width, distorted colours), so not sure whether that was a proper test.
