Comment 6 for bug 1465440

Hi, Sorry for chiming in late. The original idea behind using the "shared" attribute was to cover the use case where an operator owned firewall resource could be shared between tenants. However, this has data-path implications beyond just the sharing of the resource in the DB, and was difficult to achieve within Neutron. Hence we decided to keep the attribute for future use (and mark it as "invisible").

If this translates to a "maybe" status in the UI, I definitely agree that its confusing. I would recommend not exposing it to the user until its actually used. Of course, one could argue why we should have this attribute at all in the first place if its usage is not anticipated in the immediate future.
