I don't know of a script that would update this automatically, but the Gerrit feature seems pretty close: https://gerrit-review.googlesource.com/Documentation/user-submodules.html ; and it is possible that some Android tooling exists around the repo tool: https://source.android.com/source/developing.html

I think it is fairly easy to setup tools that do that, it is harder to do it reliably (i.e. handle concurrent push in clang and llvm for instance), or what if the server-side script fails the update because of a network issue?  Maybe it is not very important and one commit won't be part of the "global numbering"? Alternatively the push can be "failed" in such cases?
