Administration Guidelines and Recommendations

Are there guidelines or recommendations as to how one should structure the administration of Windows Azure services aside from what I'm finding here? -- http://msdn.microsoft.com/en-us/library/azure/hh531793.aspx  I need clarification on what happens if I use all Organizational Accounts for Azure administration, as is suggested in the above link, and then my Azure-hosted ADFS farm craps out leaving none of my administrators able to authenticate to manage the Windows Azure account.  Should we be adding a backup non-organizational Microsoft account as a Service Admin in order to protect against this possibility?
