To not start a new topic on this, I've had a similar concern recently for my 7D as well.
I like my focus peaking but I don't like how it burns onto my image sometimes and I have to rely on post to fix it or it just stays there regardless.
I would like to add to the option here to request the ability to turn off focus peaking whilst recording and not GLOBAL draw so that way I still have my audio levels, visual information, and crop marks because I don't shoot 16:9 ratio.
