I’ll clarify: with Justin’s monorepo proposal we would have a single repository with all the llvm-projects inside.
There is a natural cross-project synchronization since we share the repository.

While this repository would be the “source-of-truth” like SVN is today, and be read-write for developers, we would be able to continue to update the separate existing read-only repositories (http://llvm.org/git/llvm.git <http://llvm.org/git/llvm.git> http://llvm.org/git/clang.git <http://llvm.org/git/clang.git> etc.).

When exporting a commit from the monorepo to one of the read-only repository, it should be possible to generate a “git-svn-id”-like the same way we’re doing when exporting from SVN today.

Make sense?
