So what do you do with deleted submodules?
You wouldn't want them to still sit around in your working directory,
but you still have to preserve them.

Now that is a tricky one.  Mind you, I think that problem exists for any 
implementation.  I haven't got a good answer for that.

That suggests that it is probably better to separate submodule repositories
from their checked out working trees. Why not put the GITDIRs of the submodules
in subdirectories of the supermodules GITDIR instead?

Why not simply use a shared object database instead?

Sure. I have no problem with this.

But can we go one step further?
AFAICS your submodules store the .git/ directories of submodules directly
at submodule position in the working tree - but you have a link .git/objects
into the object database of the supermodule.
When the user wants to delete the submodule, he would remove this .git/ directory,
too. So you loose the .git/refs of the submodule etc. I would suggest to put
the submodule .git dirs into the .git dir of the supermodule.
