I copied this function from classic codegen so I did not think that much about it, 
I am not sure if I understand you correctly but are you suggesting to only use getBestDynamicClassType and not use the  getCXXRecord ? 
because as per my understanding both are serving different purpose, getBestDynamicClassType as you mentioned get the dynamic type. meanwhile in getCXXRecord I am getting the static type. both together is helping to determine if the function in the same class or I would need some pointer manipulation which currently not supported.
