I've used submodules a little bit and in some sense it seems to already implement core.useTotallySeparateRemote. So from my perspective trying to make this change significantly different this isn't worth the effort and I'm not sure I have the expertise to do it well. Is there a roadmap and or timeline for Git 3.0?
