> The current implementation of certain mod_cluster proxy operations are registering potentially dangerous rollback handlers. They are making an assumption what was the state of the system prior to the operation.
> For instance, if the proxy was already disabled, and a disable operation is called which intermittently fails, a callback handler will be called which will enable the proxy. This is dangerous as attempting to disable an already disabled proxy may potentially enable it.
> This behavior should be removed.
