Yeah, I think I agree. From the discussions so far, I think that we should definitely aim for making pie the default for everyone (on arches where it makes sense), but doing it in the gcc-6 now which has seen only a short period of testing so far seems a bit hasty based on data from the messages that I've seen in these threads so far.
