The issue with that kind of distrust by default is that it's not <br>
sustainable... In a large project you can't have every individual review <br>
everything because they trust noone else.<br>
<br>
That is why in OpenStack we instituted a culture of "trust by default, <br>
then escalate to PTL or TC if shit ever hits the fan". And the fact is, <br>
the PTL (at team level) or the TC (between teams) rarely had to <br>
arbitrate conflicts, because there aren't so many conflicts that are <br>
escalated rather than solved by consensus at the lower level.<br>
<br>
Restoring "trust by default" between placement and the rest of Nova <br>
seems to be the root of the problem here. In a community, it's generally <br>
done by documenting general expectations and shared understandings, so <br>
that you create a common culture and trust by default people to apply it.<br>
<br>
What would you suggest we do to improve that in this specific case?<br>
