cinder-manage service list shows happy for uninitialized driver

If there is a problem with a cinder driver not initializing correctly, but the c-vol service is up,
cinder-manage shows the cinder-volume service State as ':-)'

For example,
  If I try and configure the lefthand driver with an improper setting, such as lefthand_api_url = http://bogus.url

The service comes up, but the driver is left uninitialized.

And later when get_volume_stats() is called:

The c-vol service is up, but the driver can't accept provisioning requests and can't do get_volume_stats().

cinder-manage service list shows it's happy.

Shouldn't we say it's somewhere between XXX and :-) ??
