"Nose affair" option instead of feature (disabling ISO + WB buttons)

Please, describe the enhancement of feature requested below:

Use Case: While metering in the viewfinder on a stock 400D, I would normally 
"Push the ISO (UP) button with my thumb while scrolling through the ISO ranges 
with the front control dial with pointer finger" - however I have to pull may 
head back to the LCD to see this change.

I see that this feature was "removed/disabled" per the "nose affair":
"While looking through the viewfinder, the ISO and WB buttons become inactive. 
This is done to prevent accidental changes to camera settings from pressing 
your nose (or cheek) up against the camera body." -

I would like to request this change be an _option_ (instead of a 'feature'). 
Possibly enabled/disabled under the "Settings" or "Parameters" menu.

(because cannot hold-down ISO button with thumb when need to use Left-Right to 
change ISO, instead of using main dial and pointer finger to change ISO)
