We've been closing these bugs as CLOSED/WONTFIX, see https://bugzilla.redhat.com/show_bug.cgi?id=1464606, because of concurrency issues. Now that we have validating webhooks as GA, we can implement a more stable solution. But it's technically a RFE.

Michal, do you have a customer that requires this feature? A ticket + (short) business justification would help.

Hi Jan, actually I don't have a ticket. 
I just run this test regarding the documentation:
https://deploy-preview-29269--osdocs.netlify.app/openshift-enterprise/latest/storage/container_storage_interface/persistent-storage-csi-ovirt.html
it mentions there that user can create only one default storage domain.

Moved this over to an Epic on the storage board (https://issues.redhat.com/browse/STOR-545), will close this bug as a result
