Sorry, I just went and re-read your original post and think I had misread your intent. AFAIK, the Course Creator does not, and should not, get access to the Site Admin block. If you have set, say, yourself as both a Site Administrator and a Course Creator in a Category, then you, as Admin will see the Site Admin block but that Role overrides the Permissions with its ":goanywhere/doanything" Capability. Another Course Creator won't see the Site Admin block at all. The only people who should see the Site Admin block are the Site Administrators.
Some people here have given users Admin privileges in a Category, but I am pretty sure that that can no longer be done, which is why the Role of Manager was created. That Role can only Administrate the Category it was created for, nowhere else and it still can't see the Site Admin Block.
