It is quite unlikely that GitHub will allow LLVM (or any other project) to run arbitrary post-receive hooks. It is far more likely that they will give an option that disables the merge button in PRs. It is already possible to prevent direct pushes to master by anyone, so this would be a very small change (literally disabling one button in the UI). <br></blockquote><div><br></div><div>Disabling (or really, changing the semantics of) the merge button is actually a standard project setting for all GitHub projects, even personal ones.
