Looking back I just do not understand why git came up with this awkward mess of submodules. Instead it should have a way to say that a particular directory is self-contained and any commit affecting it should be two objects. The first is the commit object for the directory using only relative paths. The second is commit for the rest of code with a reference to it. Then one can just pull any repository into the main repository without and use it normally. git subtree tries to emulate that, but it does not scale to huge repositories as it needs to change all commits in the subtree to use new nested paths.
