PR #4586 introduced this property with default as `true` to keep the behavior; however, I also agree with @sbrueseke. With default as `true`, we are delegating to ACS the decision of rebooting the host, which might not be correct in several cases. I am inclined to make this property `false` by default and focus on alerting the operators about the situation, so they can take the right action over the environment. A redesign of the feature might be needed; however, we need discuss it first.
