It is very tempting to use that function. However it was introduced
specifically to not do that. ;)

See the series that was merged at 5aa0b6c506c (Merge branch
'bw/grep-recurse-submodules', 2017-08-22), specifically
f20e7c1ea24 (submodule: remove submodule.fetchjobs from
submodule-config parsing, 2017-08-02), where both
builtin/fetch as well as the submodule helper use the pattern to
read from the .gitmodules file va this function and then overlay it
with the read from config.

This could be a preparatory patch, but including it here is fine, too.

I think they were separated for the reason outlined above, or what Brandon
said in his reply.

I think extending 'repo_read_gitmodules' makes sense, as that is
used everywhere for the loading of submodule configuration.
