It’s worth noting that the current permissiveness is quite new in the overall history of the project. The reality is that the LLVM community has discouraged automated and/or bulk changes of any form for a very long time, including changes generated by tooling as straightforward as a sed script. When such changes have been allowed in the past, it has been after receiving prior approval from the community. I view AI-generated changes as falling into precisely the same bucket.
I will restate my outlook from the earlier thread: while being inclusive and welcoming is a goal of the LLVM project, it does not supersede the goal of building a suite of compiler & toolchain components that benefit our users. Most of the time these goals are not in conflict, but (again IMO) an overly permissive AI contribution policy betrays the duty of care we have to our users.
