These are good arguments, but you are still being way too optimistic
when it comes to the state of drivers. 
      * Intel drivers are in a terrible shape, and it’s a nightmare to
        get a kernel+X combination that works with all adapters. 
      * Radeon KMS drivers are very slow (too slow to run gnome-shell,
        at least) and still stabilizing. 
      * Nouveau is still experimental. 
      * Non-free drivers are terribly lagging behind in terms of
        non-core functionality (RandR? Ha, ha, ha.) 
      * Hardware from manufacturers other than the big 3 has zero

This is easier said than done. And if VMware has 3D support, it is still
very unstable. Which is expected when you try to access the same
hardware with different drivers in the host and the guest, both as

You are also forgetting the trend towards thin clients. The protocols to
display 3D remotely do not even exist. Everything has yet to be invented
if you want to see 3D on what will be the standard desktop for an
increasing part of our users.

As things are going, you are leaving us no choice but to keep shipping
gnome-panel by default for a very long time, unless we want to provide
two radically different user experiences.
