I intentionally widened the Q on my touring bike because I started the trip on the last weeks of February and wore shoe-covers to keep mt feet warmer and drier,
with pedal extenders , so those shoe covers did not rub against the crank arms , with every pedal stroke .. you get used to it .. Bike tour was 3 seasons long..
I now have a somewhat wide setup to get the chain-line right, for the requirements of the Rohloff hub in the back..
Single chainring on inside of crank spider , disc chain guard on the outside...
