I just posted this question on the ACES website: http://acescentral.com/t/why-utility-raw-as-reference-for-aces1-0-3-and-not-aces2065-1/1378
It seems like it's not just me that is unsure, how OCIO decides, which colorspace in a config is used as the reference space, that all other colorspaces are related to. And what excact purpose the 'reference' role has.
Could you maybe have a look at this and shine some light on this topic?
