Hmm, to me it looks like passing the --reference option to the clone
run in the submodules doesn't make much sense, as that would make
all submodules and the superproject use the same alternates. And as
far as I know sharing objects between different repositories is not
supported.

You'd have to use "git clone" without the --recursive option and
then do a "git submodule update --init --reference ...".
