The issue with that kind of distrust by default is that it's not 
sustainable... In a large project you can't have every individual review 
everything because they trust noone else.

That is why in OpenStack we instituted a culture of "trust by default, 
then escalate to PTL or TC if shit ever hits the fan". And the fact is, 
the PTL (at team level) or the TC (between teams) rarely had to 
arbitrate conflicts, because there aren't so many conflicts that are 
escalated rather than solved by consensus at the lower level.

Restoring "trust by default" between placement and the rest of Nova 
seems to be the root of the problem here. In a community, it's generally 
done by documenting general expectations and shared understandings, so 
that you create a common culture and trust by default people to apply it.

What would you suggest we do to improve that in this specific case?
