I'm not sure. Looking through the git history is difficult because they got added in https://reviews.llvm.org/D129526, but I can't find anything from before that. https://github.com/llvm/actions/commit/55d844821959226fab4911f96f37071c1d4c3268 is also pretty vague. It has support for downloading release source tarballs, so I'm wondering if it had to do with the split release/main repo, or maybe missing features in actions/checkout.
