We would like to be able to assign multiple ranks to members or a way for a member to display the multiple roles they have withing the organization. Multiple ranks can fill this purpose just fine.

In out wow guild we have ranks sth like Raid 1, Raid 2, but due to limitation of in-game guild rank system we can have only 1 rank assigned to character. Just like here. But it would be more clear when you see in forums that somebody is member of Raid 1, he is also officer and maybe Class Leader.
