Ghost- I can't agree with your point of not recognizing thermal insulation as a firestop or draftstop. I do know that these products are used for combustible construction and the Code panel obviously knows also or they would not address thus senerio in the code with the result being a derating of the ampacity.
Article 300 Section 300.21 clearly says I can use anything I want to as long as the "possible spread of product of combustion will not be substantially increased"
Of course if it's a fire rated assembly then we are required to us products that would maintain the integrity of the assembly.
