I think compatibility across released versions is not supported in upstream LLVM. But downstream, there are use cases. For example, classic-flang that does not generate the implicit parameter. While we maintained this change downstream for some time, it would be very helpful for maintenance if this could be merged upstream. The change in this patch is fairly simple and non-intrusive.
