Well that's just it. With commercial raw you don't have control over the ingredients - only to the extent that you pick and chose which product you buy. 
For some of us, there's a comfort level because of supplements, and for a very few of the commercial raws, there is the pathogen-free guaranteed aspect, because of the high pressure processing (Nature's Variety, Stella & Chewy's, and Primal's poultry products). But I think for most, the commercial raws are really used for the transition to raw. We don't really know what nutrients are lost in the processing, the freezing, etc., and you're absolutely right about not having the benefit of chewing chunks and some bones.

That was fun!
