There was a big debate on here a while back and I agree with you but the consensus was that unless you know the arm and bolts to be free to move then its a good idea to slacken them off.
Its somthing LIKE this. The caliper should rotate when you pull the wheel back and when it does the torque arm should change its angle to let it, but if the bolts each end are seized then when you pull the wheel back you are loading the swing arm bolt fixing with stress, - have a look at it, a silly blob of alloy with a hole in it.
Last year I took mine off to respray and cleaned and lubed up the pivot points on the arm and fixing, the bolts are not threaded all the way through to allow movement when you pull the wheel back.
Although this picture was also to do with putting a 1000 arm on it shows you the weak piont (not my bike)
