bx curl /v2/users/...../spaces needs "admin" permissions

Subject: Ticket #5377-13212692 Requested Info - Client (bx curl /v2/users/... CF-notauthorized)

Unfortunately, the command needs "admin" at Bluemix level privileges. You could only ask for your own spaces. I have confirmed with the community that it is current design.
You could request for Bluemix feature here : https://ibmcloud.ideas.aha.io/

I would like to extract all roles a user has in an org's spaces, using the command (or any other):

bx curl /v2/users/...../spaces

Apparently this requires "admin" permissions which are beyond reach for Bluemix customers at this time !?
