I have never used it or needed it, so I am not a good reviewer for it. I had thought it was a strange feature flag, but I had been forced to preserve it when I touched code in that area because of both tests and user comments when I accidentally broke it in https://reviews.llvm.org/D89613#2336529. So I am in favor of removing it, as it seems undocumented and minimally tested, but I was aware that some folks seemed to find it useful.
