I am not aware of anyone actively using the pass or working on it. If there are users, I’d love to hear, but otherwise I think we should consider removing it. It is a source of confusion and requires API updates from time to time.

I put up a patch to remove it, with some more details:https://reviews.llvm.org/D84447 <https://reviews.llvm.org/D84447>
