user_permission does not list namespace permissions

The user_permission command does not list namespace permissions:

For example: if I create a new namespace or use an existing namespace and grant a user privileges to that namespace, the command user_permission does not list it. The permission is visible in the acl table.

Example:
hbase(main):005:0> create_namespace 'ns3'
0 row(s) in 0.1640 seconds
hbase(main):007:0> grant 'test_user','RWXAC','@ns3'
0 row(s) in 0.5680 seconds
hbase(main):008:0> user_permission '.*'
User Namespace,Table,Family,Qualifier:Permission
sh82993 finance,finance:emp,,: [Permission: actions=READ,WRITE,EXEC,CREATE,ADMIN]
@hbaseglobaldba hbase,hbase:acl,,: [Permission: actions=EXEC,CREATE,ADMIN]
@hbaseglobaloper hbase,hbase:acl,,: [Permission: actions=EXEC,ADMIN]
hdfs hbase,hbase:acl,,: [Permission: actions=READ,WRITE,CREATE,ADMIN,EXEC]
sh82993 ns1,ns1:tbl1,,: [Permission: actions=READ,WRITE,EXEC,CREATE,ADMIN]
ns1admin ns1,ns1:tbl2,,: [Permission: actions=EXEC,CREATE,ADMIN]
@hbaseappltest_ns1funct ns1,ns1:tbl2,,: [Permission: actions=READ,WRITE,EXEC]
ns1funct ns1,ns1:tbl2,,: [Permission: actions=READ,WRITE,EXEC,CREATE,ADMIN]
hbase ns2,ns2:tbl1,,: [Permission: actions=READ,WRITE,EXEC,CREATE,ADMIN]
9 row(s) in 1.8090 seconds

As you can see user test_user does not appear in the output, but we can see the permission in the ACL table.

It would be nice to be able to see namespace permissions via the user_permission '.*' command as scanning the acl table is not the recommended way to view object permissions. Especially if one is looking to access base via a shell and collect ACL information.
