Interesting idea.

How does this work (1) if the submodule checkout changes with the supermodule checkout? You still would have to store the modifications somewhere. (2) on platforms which do not allow symlinks

A workaround for problem (1) would be to create multiple checkouts of the
same submodule if modified, e.g. in .git/submodule/$name/$sha1 .
 
Allowing people to work like that is nice, but it should not be forced.
It would also be nice to allow the user to specify another place where
submodule checkouts are to be stored, e.g. when multiple supermodules
share the same submodule.
