I am not an expert and I'm not necessarily disagreeing with you because I don't really know the answer to this. My initial thoughts though are that while an mRAW file DOES contain less information overall, it's in a smaller dimension photo so it might not resolve less detail than a full RAW file. On the 7D a RAW file is 5184x3456 and an mRAW file is 3888x2592. When viewed at 100% at the same dpi my thinking is that both types of files would give you about the same number of lines per inch, thus giving the same resolution of detail. I could be completely wrong though and probably am but that is just what I was thinking.
Well, technically the full size RAW will give you a better resolution. However, in the real world certain things work against it: inferior lens, motion blur etc. So quite often there is no difference between an mRAW and a full RAW file because the subtle details of the pictures get wiped out by some external factor like bad lens, atmosphere (tele lenses), motion blur, challenging AF conditions, etc. So you can take the fullest advantage of the full RAW vs mRAW if the circumstances are good for a nicely detailed shot. Most of my shots are full RAW, but there are occasions when I switch to mRAW because a full RAW would be overkill, I wouldn't gain any more detail in the full RAW shot anyway.
