Default Question about new-for-1972 VIN coding

I’m trying to determine GM’s rationale for adding the engine code to the VIN sequence beginning in 1972. While I believe it was used to simplify the way insurance rates were determined/assessed for a given vehicle, I’m hoping to find something concrete from GM or a known-reliable source.

Might anyone have anything they can share?

From my google search I believe it is related to the Society of Automotive Engineers, in particular SAE J273A. Havent been able to dig up the details yet but found the link below.
