In these diamond scenarios, it is really easy to end up with a ton of LLVM repo clones on your workstation. In general, though, I do prefer the simplicity of clone, submodule init/update and build.

Sure - no doubt.  I’m not a fan of submodules either in practice, but having one that you manage seems to be working ok.  It is just a balance between all the other suboptimal answers to this problem.
