Of course, but all operations federated through the engine will have a
downtime.
these are: starting, (hard)stopping, deleting, creating vms, etc.
furthermore regarding hosted-engine: you don't just have to wait
for the service to restart (that's almost always a matter of seconds)
but for the whole vm to boot, which takes much more time and more
things can go wrong during this process.
So I think there is still room for improvement.
