CPA value in nonfinancial advisory

In order to make partner, one would need to be a CPA. Which makes sense when the ranks usually stop at principle/director under advisory since many don't have an accounting background. I have yet to meet/know of/heard anyone who has an actual "partner" status in advisory. 

So say I'm working with a nonfinancial advisory LOS specializing in SAP, and I have a CPA, which adds little, if any, value to the actual work. Would that be considered an advantage internally in the long run during promotions? Assuming advisory structure is the same as assurance and tax.
