Nobody downstream has to adopt the new structure, I believe it is possible to extract only the “llvm” commits from the new repo and rebase them on top of the existing llvm repo.
This can be done on the fly by you CI, but it is also a deterministic process, i.e. you can restart from scratch anytime (assuming you have the original llvm.git repo and the new one).

I have no idea what you mean here?
