Dang it, I really liked the idea. But now GitHub is stuck waiting for the "Expected" build-docs workflow... and if I remove it from the expected checks, then I wouldn't be able to auto-merge other PRs once checks are passing, because it would merge with just the tests, even if docs are broken. 😔

So for now I'll have to leave it as it is and pass on this PR. 😔 But thanks for the effort! ☕
