There are two major issues when deciding on a height requirement.
The first is geometric. You can work out the proportions of a human body and figure out where the center of gravity and where the joints are going to be based on a person's height. That information can be used to insure that people in a certain range of sizes can be accommodated. One of the difficulties is the broad range of sizes that people come in; using a higher minimum height requirement reduces the variation since most people do not get to be much taller than about 78". Personally, I think this is more of an issue for rides that have shoulder bars than for rides that use lap bars, but there may be a girth issue as well on MF; also there may be some concern with the position of the headrest and making certain that the rider's head does not end up in the gap at the top of the seat.
Of course, the other issue is maturity, in that a young child is more likely to panic and do something stupid than an older person (12YO vs. 8YO, for instance). I'm not sure that I agree with that assessment either, as I have seen adults do some stupid things as well.
So CP has finally announced the restriction at 54". I'm sorry to hear that. The announcement was just added to the web page today, and it suggests to me that the construction diary entries are about two testing stages behind reality. I wonder if this means the return of the Tweener ticket, now that there are *four* rides that the 48"-52" (three for the 52"-53" crowd) cannot ride.
