Cannot remove and re-add socket-binding group

Error message when trying to (remove and) add a socket-binding-group in domain mode:

First remove:

{ "operation" => "remove", "address" => [("socket-binding-group" => "standard-sockets")] }

Result:
{
"outcome" : "success",
"result" : null,
"server-groups" : {"server-group-1" : {"server-1" : {
"host" : "master",
"response" :

{"outcome" : "success"}

}}}
}
Now add again:
{
"name" : "standard-sockets",
"default-interface" : "public",
"operation" : "add",
"address" : [

{ "socket-binding-group" : "standard-sockets" }

]
}
Result:
{
"outcome" : "failed",
"result" : null,
"failure-description" : "JBAS010839: Operation failed or was rolled back on all servers.",
"rolled-back" : true,
"server-groups" : {"server-group-1" : {"server-1" : {
"host" : "master",
"response" :

{ "outcome" : "failed", "failure-description" : "JBAS014749: Operation handler failed: Service jboss.socket-binding-manager is already registered", "rolled-back" : true }

}}}
}

For me, this seems a bit strange. If an error shall be produced, then it should be thrown when removing the socket-binding-group, as there is a server running referencing the socket-binding-group via server-group. But if the socket-binding-group can be removed, it should also be possible to add it again (possibly with new defined socket-bindings in the group, then trigger a restart of the server in order to take the newly configured ports into account).
