/subsystem=deployment-scanner does not list the currently used scanner

[domain@localhost:9999 subsystem=deployment-scanner] :read-resource
{
"outcome" => "success",
"result" => {"scanner" => {"default" => undefined}}
}
sub resource scanner=* can have multiple entries and thus the base should have a way to determine the scanner used.

IF there can be only one scanner (an :add method is present though), then please put all attributes from /subsystem=deployment-scanner/scanner=default in /subsystem=deployment-scanner and remove the sub-resource.
