If we would shutdown the provider an authentication failure, and
engine's admin has no access to engine's host super user shell, there is
no way to recover for engine's admin.
Even the authentication failure might be triggered from outside oVirt
engine, shutting down the provider will disable the start of VMs with
OVN networks.

What is you opinion about the approach if the request comes from inside
engine, e.g. by SyncNetworkProviderCommand or other operations, the
provider object inside engine would be marked as invalid on
authentication error and block all interaction until the
credentials is updated?
