Can you send another PR for the basic/most indivisible interfaces with mock implementations in unit tests? I think you could then send specific implementations one by one. And finish with `llvm-cas` and the LLVM C APIs? My impression is that everyone agrees that we need all this.

Hi @aganea Thanks for helping with the review! I was distracted with other obligation that I temporary unable to follow up with the reviews and I definitely intended to pick this up ASAP. Note this PR was created just as we transition to GitHub PR that there isn't a clear workflow for how to handle a big PR like this. I was breaking up the big commit into smaller reviews (like https://github.com/llvm/llvm-project/pull/69528) while using this PR to provide a larger context. I might take some time to rewrite this PR using `spr`. I will remember to add you as reviewer in future PR.

Cool! Glad to see more community members are doing something similar and we hope we can work together!
