Canon Mode Dial Modification

Canon has announced that it will offer a $100 service to the 7D and 5D Mark II camera bodies. The modification includes adding a lock mechanism to the mode dial. Some users have reported that the dial could easily turn to a different setting while using the camera. On Canon's website, it states:
"This modification is available, for a fee, to owners of these cameras who would prefer a Mode Dial which locks in place and can’t be accidentally moved during normal camera operation."
The words "during normal operation" make this seem like a flaw in the design, but in reality most users do not need a locking dial. Still, many will attest this should be a free fix rather than an "upgrade." And the feature does come standard on the 60D. I think it would be great of Canon to give new customers the option when ordering a body, which would carry a much lesser fee.
