Ok, I understand. I find it a little curious though, since I don't see
what the risk is in allowing startup as long as the cluster is quorate.
Imagine you have a multi-node cluster that suffers a total outage - a
wider infrastructure problem or some kind for example - and upon
recovery one node is still out of the cluster for whatever reason. 
It's pretty common in my experience that larger outages result in many
smaller resulting issues that take a while to clean-up.
