I know what you're saying, and why, but you have to ask yourself the question:  Is there never going to be a time where I may want to have the camera off, just for a brief period?

If that is answered with, "yes," then you need to consider whether it's possible to mask the offending key that's currently being accidentally pressed in such a way that it cannot be.  Very often that's so much easier to do, and allows quick access to it for the rare occasions where it's needed, than remapping keys is.

Science has become just another voice in the room; it has lost its platform.  Now, you simply declare your own truth.
