If this works for you, I am all the more happy for you.  I thought that 
you wanted to be able to go to a certain revision and get the same working 
directory/directories.  (But that is not what you get...)

Strictly speaking, you do not have to move it outside.

No need to play games with GIT_INDEX_FILE, as far as I can tell.

If you plan to do away with subB, you do not need to specify it... Just 
use FETCH_HEAD, directly after the fetch.

The git-cherry call is not really necessary, right?  The two repos have no 
common history (not even common patches).

Besides, I think that what you did is just a complicated way of doing a 
rebase.

But be aware that checking out older versions of the superproject will 
still have the submodule!
