TL; DR
Consider the stakeholders whose active buy-in you need.
Now think about those others who could cause you trouble if trust is lost. That is likely a bigger group.
That bigger group is likely one with whom you don't have many shared experiences. But consider whether to add those experiences because communication and coordination alone are only enough to produce trust when you work in stable settings. When it's your job to change an org, you need much more trust, and that likely takes more shared experiences than you might even consider.
Communication alone is unlikely to be enough, unless you use tons and tons of it, in all kinds of ways.
