It seems that you are only looking at the submodule config from a

Haven't looked further in the patchseries so maybe that is somewhere

It turns out that in later patches we pass in null_sha1 only, which is
looking at the config and possible overrides.

I'll refactor to take no sha1 argument and use null_sha1 here directly.
