Sure, I realise that if you have an extremely basic pipeline without forwarding then it does matter. I just didn't think anyone seriously cared about such microarchitectures in this day and age, or if they did then they at least didn't expect any kind of half-decent performance out of them. Not against this change, just surprised it's ever particularly noticeable.
