This brings up a good point. Why are we following the latest pep8 release so closely in Nova? The latest release is hardly a month old and we are already using it? We aren't necessarily doing the same for all the other OpenStack projects... (nor am I suggesting that we do). So why Nova?

I'm not convinced the latest pep8 "features" really provide us enough benefit that we need to bump our pep8 baseline every month or two.  in fact they may be hurting us in terms of churn, extra work, back-portability of upstream patches, etc. Ultimately is tracking the latest pep8 really worth it?
